(This was dictated to me by my husband, who has eaten at Bellini a lot, with the caveat that he's usually there for lunch. YMMV since you'll be having dinner):
Compared to places like Osteria or Amis, the food is unadventurous, but can be tasty. The tables are very close together. They offer two soups of the day and usually 2-3 specials. I've found the soups to be very good; the lobster bisque, if they have it, is full of flavor but salty. The seafood salad is good, as is the penne Bellini.
