Go to Ana's in Davis Square or the MIT student center. Best burritos ever.
All the mexican places around here (downtown at least) are hoity toity and expensive.

Also some great burritos at La Bamba on Old Middlefield in MV. The new location on Castro is pretty tasty too.
Anna's at MIT definitely holds its own though.
