I clearly look Uzbek but the waiters keep talking Russian despite that until I myself start talking Uzbek. It's so frustrating.. And when a waiter who clearly is ethnically Russian talks in Russian, I feel uncomfortable to refuse to speak Russian because I feel like I'm oppressing the minority. They've got to fix it. Not to mention that it took them about 1 minutes to come and take the order in the first place.
It's a great place, good environment, polite and professional staff, perfect for small talks, lunch, business meetings etc. love being here especially in the good weather and sitting outside.
