DB has a very nice(and very reasonable)prixe fixe three course early dinner.Portions are not huge-but might just be what you are looking for.
We were not thrilled with the service either-started off just fine-then went downhill to the point that I had to get up and chase down our waiter to get the check.It can get VERY loud in DB also-so patio dining might be a good idea.
Bartolotta is much better than Sinatra=but the wine list is ridiculously overpriced(as is the specialty whole fish dish)but if you order wisely you can get out of there without having to mortage the house.
