My husband and I have eaten there many times and we've often taken guests.
The food is excellent and the service almost always impeccable. It's a lovely place with great ambience. Biba herself is friendly and often comes by the tables. Food arrival is usually timed perfectly. The servers are attentive and friendly without being intrusive.The one exception to otherwise perfect service was a year or so ago when our server who had been attentive and efficient during the meal pretty much forgot about us when we wanted to order dessert and pay the bill. But that was the one exception in all the years
we've been dining there. I highly recommend Biba's.
