Union Square Pizza & Kitchen

Jeff Chen

Best pizza in San Francisco! Union Square Pizza & Kitchen was fantastic from start to finish. Ramy provided great service—friendly, fast, and made the experience even better. The New Englander pizza with hot honey was outstanding, with the perfect balance of crispy crust, savory flavor, and a touch of heat. The Chicken Bacon Ranch (CBR) was rich and satisfying, and our custom garlic pesto pizza did not disappoint. They had baklava which we had to give it a try and it was excellent and the perfect sweet finish. If you’re looking for the best pizza in San Francisco, especially near Union Square, this place is a must-try. We’ll definitely be back! 🍕🔥

We came to San Francisco with our family to celebrate the New Year. At first, we went to another place, but we didn’t like the food selection, so we decided to leave. By a happy coincidence, I then found this place on Google Maps. From the outside, it’s completely unremarkable, literally hidden within the structure of a building under renovation. When we walked inside, we honestly didn’t expect anything special — the interior is very simple, even a bit cheap-looking. But the pizza was absolutely incredible. We ordered two pizzas and also tried the Italian soda separately, and it turned out to be a real discovery. Despite the modest and somewhat gloomy interior, this place is definitely worth the money. That pizza made our day truly festive and became the perfect ending to our New Year’s celebration.

We got a New Englander pizza. They sell full pizzas and by the slice. Speedy service, greasy & delicious pie.

While everyone's experience is different and so is mine. I am expressing what I experienced. We came the night before and were walking across to the Hilton for an event Saturday morning. While checking out Hilton by walking came across this spot and timing said open till late. So we stopped by after rounding up Union Square and picking up dessert from Cheesecake Factory. Pizza to go was our plan for dinner. Ordered a margherita pizza to go with extra onions and garlic and was delivered in 10 minutes while we waited in their seated and eating away on our dessert. The pizza looked great and tasted even better when we had it in a few minutes after we reached our hotel. The place is clean and tidy with restroom access but we didn't use it . Cost wise was nominal for Union Square area . Will definitely come again for their delicious pizza.

On my first visit, Ramy and crew were quite accommodating to my special request for cheese on only one side of the Backyard BBQ pie. Fun dining area with a couple of tall counters and bar stools as well as standard height tables and chairs. Everything we ordered was yummy. I will be back soon!

Was craving a slice of pizza and needed something close to where I was staying. Wow what a find! I got the margarita pesto and it was exceptional. Vegetables fresh, crust amazing and tasted delicious.

Absolutely phenomenal. The crust was perfectly crisp on the outside and delightfully chewy on the inside. The toppings were fresh, generous, and full of flavor. We tried vegetarian and pepperoni’s it was a masterpiece (the balance of tangy tomato sauce, creamy mozzarella, and fresh basil was divine) What sets this place apart is not just the food but the attention to detail. The staff were friendly, attentive, and genuinely passionate about their craft. The variety of options is also worth mentioning. If you’re in San Francisco and looking for exceptional pizza, don’t miss this place. It’s the kind of spot that leaves you dreaming about your next visit. Highly recommended!

Got some slices for takeout and it was super quick! The pizza was great- $7 a slice, not too greasy, and both sauce and crust were really good. The guy was super nice and said it’d take 10-15 minutes if I wanted a whole pie, but it took only a few to heat up the ready slices. The inside was nice and I’d sit to eat if I had more time.

Sabastion was very friendly and helped us alot when we couldnt decide how much we needed to order. We tried 2 pizzas and a calzone, the pizzas we tried were bbq pizza and a the CRT...ooo they were so delicious and were loaded with lots of toppings (calzone was bomb to) After having both I'd say the pesto base pizza def wins for Me but the mild sweetness of the bbq was amazing still!

Best pepperoni pizza i've ever eat!!! Hawaiian pizza was normal. Staff were very kind. I want to go San Francisco again beacause of this restraunte.

I enjoy the quiet from time to time and having a new gem in town that is only 3 breaths and a step from Union Square gives me hope. They had me at first visit with their version of "the best" cup of coffee I have ever sipped through; evidenced by the picture I posted below this platform. It's buttery flavor and rich kiss bring me to Inciza, Italy and the memories of Italian life and all its fruits for the world to enjoy. I have not had a meal here yet. They boast a traditional pizzeria cuisine that is built around an "on the go" SFer and provides a small, simple eating area for a 1 to small party. They also have ice cold Peroni beer if your day demands a quick one. Do stop and enjoy a peaceful break from the noisy biproduct of downtown. And next time you go to Starbucks for your regular coffee, make a detour up O'Farrell about one block (284 O'farrell) and you'll be delighted with my suggestion. See you soon.

Pizza was delicious! The crust was flakey and buttery. Thank you Henry for the sample. 🙏

Wonderful Pizza!! Fast, friendly service.

Wow, we are completely blown away!! I work for a non profit called Dream on 3, and we make sports dreams happen for kids with life altering conditions. Our dreamer loves pizza, so i did some research and saw that Union Square Pizza was THE place to go! we contacted the owner, Ramy, and WOW did he exceed our expectations! We were greeted with excellent service, amazing pizza, and little touches to make our dreamer feel so special. We talked about the quality of the pizza and friendliness of Ramy all week. We couldnt make our dreams come true without partners like this, so we are so thankful. I would highly recommend anyone to go and try their amazing pizza. The pepperoni was amazing and definitely a fan favorite! Thank you, Ramy, for treating us so well and loving on our dreamer!! We will be back!!

Surprisingly good pizza! We ordered a pizza for dine in and it was made fresh for us and the staff was really friendly to us. Wait time was very short as well.

Great, cozy spot for a casual team/ group dinner of ~27! Pizza was incredible, salads and gelato were good too. Ramy and staff made it easy to set up in advance, so the food came out when we arrived. They also advised on how much food to buy- we had exactly one slice of pizza left. Thanks USPK!

Found this place on the fly and walked in to the BEST customer service ever. The gentleman suggested an alter to my order to save money. The pizza came out fast and hot. And it tasted amazing.

Very good pizza. Some of the best, actually. Excellent sauce flavor, and high quality ingredients. Expensive for what you get, but this is downtown San fransisco. Friendly and helpful staff both on the phone and in person, which is unexpected of a large city restaurant/pizza shop. Would recommend if you dont mind spending ~$30 for a medium pizza.

Pizza was quite good. However we ended up paying around 50$ which I thought Is insanely pricey for 1 pizza (shared between both of us). The apple juice was top notch. I wonder if apples from California because fruit here seems to be top spec.

This new pizza place is located right on the corner across from the Hilton Union Square. The ingredients are fresh and everything is made to order. I didn’t like that you must scan a QR code scan to see the full menu, but they do have signs hung with part of the menu. I ordered both a pizza and a chicken Alfredo pasta to try them out. Both were very good. The chef was very nice and checked on us personally. I travel to San Francisco fairly often and will be returning.

Pizza tasted good but wow, it was pricey. Nearly $30 for a (medium sized?) cheese pizza and a single can of soda. Seems excessive. Should've only been $18 or $20 for the pie. Service was quick and friendly.

The perfect place to eat when you’re exhausted from conference attending. I have been stuck on east coast time the past two days and just couldn’t handle a complicated dinner. This was perfect and the folks running the spot were so kind. Amazingly easy access from the conference center across the street. Thank you!

I am sorry but there is no way the pizza I received is worth 40$. Yall are tripping. The ingredients are fresh and the overall taste and quality are not worth 40$ in my opinion. This is what you call extra cheese? Word? Like I always bring up like a broken record the value proposition is severely lacking. This was not a good experience sorry to say. The pizza was good but not great. Stop charging excellent pizza prices for mediocre pizza man. If you have read this review thank you. You have been great I have been Mike C!!!

Long wait time after placing the order and the pizza arrived cold. The place is not bad but we were super disappointed with the quality of service and the quality of pizza. The server didn't see to care.
