I go here all the time and the staff are nice. This place has a great atmosphere. The food is consistently good. They use fresh pasta for all the primi piatti. They make their own veal demi-glace, which is a real treat. It is a very popular place and sometimes it is hard to get a table or space at the bar.
I had one bad experience of diarrhea from the "Bosco" field mushroom pasta, so you might want to avoid that one. Probably a one-off. It won't stop me from going back though.
