We eat at Gratzzi a few times a month for two reasons; the food and the service. Dominic and Kevin are class acts. The servers are always top notch, courteous, and thoughtful. The food is alway impeccable. During the summers, they have their tour of Italy specials and you can sample food from all the various regions of Italy. They go out of their way to provide great service. As with any restaurant, there have been the rare occasions (two times in the past 2 years) that my meal was not up to par. They repalced it quickly and efficiently with many apologies. We've been to Roma many times and back in the States, nothing outside of NYC can even come close to what we had in Roma.
Pros: food, service, staff, ambience
Cons: can't honestly think of any
