I'll be visiting Boston for the first time with my brother and I wanted some recs geared towards college students -- specifically budget friendly and unpretentious. We'll be staying in the financial district (near Post Office Square), which I understand to be mostly dead at night, but we're willing to go further afield to get away from standard tourist fare and chains.
I've been told that I can't leave without trying:
Pizzeria Regina in the North End
Mikes Pastry (specifically Cannoli)
And in Cambridge:
Bartley's for hamburgers
Christina's Ice Cream
Does anyone have any other suggestions? A seafood place that can accommodate a vegetarians would also be appreciated -- I'm not sure if the "Vegetarian Box" at Legal Seafoods is going to cut it.
