Garbo's Grill - the umami burger is fantastic.
Deuce's Off-the-Hook Grill is really good upscale food but not priced like the other high-end restaurants.
Bien is an awesome grab and go lunch spot. Its in an old corner gas-station building. The Press sandwich and the shrimp or scallops in red-sauce are a religious experience.
El Siboney is another incredible cuban restaurant (sit-down). Lots of locals since it is several block away from Duvall.
Whatever you do - rent bicycles for the entirety of your stay. Especially if it is hot/humid. the first time we visited we waited 1.5 days to rent and it instantly changed the vacation (mid-July). No better way to get around quickly.
Staff - take out the trash.
