I have been to BB a dozen times over the past few years.
I give it a 4 for its great food. The omelettes are always tasty and fluffy, french toast is just amazing, and the pastries are so decadent. Cannot go wrong with the food.
I do not go more often, even though we live so close, due to the cramped space inside. There is a tiny patio area but it's not pleasant if it's super cold outside.
As well, the service has always been just meh. They never seems to be that something extra.
It is worth going for the food. If waiting and being in a cramped space is not your thing, get a baguette and some pastries to go.
