The cinnamon roll here is famed, and well worth it. The line in the morning often wraps around the outside of the (very small) store and up the street, but I was able to beat the rush on a weekday morning at about 7:30 AM.
I'm typically not a huge fan of cinnamon rolls, but this one was perfect - there is no excessive glaze, so the pastry is not too sweet, allowing you to taste and enjoy the bun itself. I would definitely recommend coming here at least once.
They don't have espresso, so plan a second stop for your caffeine needs.
