If you don't like hot and spicy beware! The tuna sandwich - normally safe, comfort food - is made with chopped chili peppers and pepper. It was lovely here last week, inedible (by me) today.
The chicken sandwich is amazing. Fresh mozzarella, bacon, on a ciabattabun. Fries are great too. If you find yourself spending a lot of time at Mass General this place is across the street.
