After eating burritos from the cart in Back bay station (pretty decent, I should add), my co-workers and I were discussing Boston's lack of food carts and trucks from which to lunch.
Around here, there are 3 in Back bay station (no more arepas though) and a hot dog guy and an ice guy in Copley. That's it.
Not that Boston has to compare itself to NYC, but you could eat lunch a different cart every day for 20 years there. And be quite happy.
Why no carts here?
