I visited Barrafina last Thursday evening and had to wait but even waiting was fun as there was a lively atmosphere and we were able to have a glass of wine and tapas. We were warned about the wait so no complaints there. Once we were seated there was no pressure despite being busy and the staff were friendly and happy to let us choose at our leisure. The quality of food and wine was superb and well worth the wait. There is a mandatory service charge which for me is the only let down.
