Went here for a drink on Wednesday night at 2330, as all other places were closed and the 5 stars on Yandex sounded great.
We were served by Marina / Марина who was kind, super professional and spoke great English.
Had cha cha (danger :D), wine and some tea and bill was not painful at all.
We couldn't sit outside because they closed at 00:00, but actually we stayed inside even a bit past.
Highly recommended after doing a boat trip of the city :)
