I keep hearing about their amazing clam pasta, but I don't think that actually exists anymore... Sigh!
Tutto is excellently located for pre-Overture center dinner, and they take reservations! So I've been there a couple of times before a show. The atmosphere is standard "Italian." The food is good, but it's not necessarily creative. It's got all your favorite staples (Alfredo! Red sauce!) and a good set of options in those sauces. They have some different pasta options too--whole wheat, omega 3, etc etc. Worth it! Large portions, a little on the expensive side, but generally a good time.
