You guys are killing me here--the Convention Center is about a 5 minute walk from Atwells Ave. and Federal Hill, where you can get the best Italian food this side of NY.
Angelo's is reasonable and has some of the best veal marsalla I've ever had.
Wise men speak because they have something to say; Fools, because they have to say something.
Mike P is right. The Italian food along that street is really great...however you might get caught in the crossfire of a mob hit so keep your eyes open and always sit with your back to the wall.
