While service for smoothies, bowls, and such isn't super super fast as others have mentioned, their offerings are tasty and consistent. Added bonus, they don't, at least, to your face, give you the stink eye if you substitute one fruit for another fruit or need to omit something from a menu item.
I often visit them on Sunday afternoons after--ahem--a little too much fun on Saturdays, for their charcoal lemonade. It's not too sweet and always kicks my hangover when I need it.
Great part of South End -- I love the energy in here. The space is always immaculate and the staff is friendly.
