You may think it's clever to call Boston by its nickname, "Beantown". The name probably came from one of the popular local favorite, baked beans, back in colonial days. Nowadays, noone around here calls Boston that any more, and the locals are liable to get upset if you do. "Hub", as in "hub of the universe", is an acceptable alternative.
While baked beans aren't hawked on the streets any more, fried dough can be found many places, along with my guilty favorite, Italian sausage.
