The 5-ounce hamburger with lettuce and tomato ($3.95) comes wrapped in paper. Fries make such a short trip from their fat bath to the table that they’re amazingly hot and crisp. You could get in and out of this funky 77-seat place in a breeze, if only the servers were as skilled as the cooks. There is also a Harvard Square and a Southie location. — S.J.
