    This was my first time dining here, and I was thoroughly impressed - especially thanks to Tania, who made the evening truly special. I was celebrating my partner’s presentation at a conference and Tania picked up on the occasion right away, bringing a warm and thoughtful energy to the entire experience. The tuna tartare was a standout; fresh, balanced, and beautifully presented. Tania recommended an N/A wine that complemented my experience perfectly, and her attention to detail throughout the meal was flawless. Exceptional service, great food, and a genuine sense of hospitality from both management (shout out to Tati, Matthew, and Mike!) and staff. We’ll definitely be back!

    Our visit was so pleasurable! Ula kept the amazing Farallons decor, which is beautiful. We were seated on the edge of the main dining room, which we had to ourselves for the first hour before it started to fill up. (Even as tables around us filled in, it was still quiet enough to have a conversation, which was nice.) Ezekiel was our waiter and he was so nice and informative. We had the bread service, which is focaccia. It was good, but honestly I'd rather have had SF sourdough or garlic bread. I had Agnolotti -- "dungeness crab ricotta pillow ravioli, rock shrimp, corn, fava bean, roasted sundried tomato sauce." It was a very generous plate and a lovely medley of flavors. My husband had the salmon -- "pan seared Atlantic salmon, cauliflower rice, kale, chickpea, corn, lobster parsley butter." Ezekiel was accommodating when we requested the salmon not be sushi and it came out perfectly. For dessert we shared a creme brulee, which was excellent, and my husband had an Affogato. It was a special evening for us, which we did not mention to the staff, and everyone at Ula made it even more so because that's the way they are. I'd recommend to anyone looking for good food in an amazing setting.
