We had a private dinner party here and I would say the ambiance was the best part of Zeffrino. Perhaps, the restaurant is understaffed, but it was reallllllyyyyyyy ssssssssslllllooooooowwwwww! So slow, I thought I'd never get out. Dinner took 3.5 hours! Yikes, but it kept me out of the casinos!
The food was ok, not great, not bad....just, ok. All in all, a very average experience.
