I have eaten at this restaurant several times in the past, either as part of a couple or a small group.
Last night, I took a party of 29 (booked about 2 months in advance) to eat in the upstairs section. We had exclusive use of the area, which was great as we had an after-dinner speaker. However, after someone had taken initial drinks orders, we were left with ONE person serving us the food. This meant that there was a 45 minute gap between the first table receiving their main course and the last table receiving theirs! Someone from my table went downstairs to get us more drinks because we were unable to order them from our table (given the lack of waiting staff) and she noted that there were 3 members of staff downstairs apparently standing around doing nothing!!
The food was hot and tasty as always and really good value but I will NOT be returning with a large group.
