Ragtime Tavern (207 Atlantic Boulevard) in Atlantic Beach is a passable restaurant, but what I like about it is their sunken aquarium room that makes you feel like you're underwater. Especially after a few of their Pacific Blue cocktails.
Sometimes they don't have the room open; if it isn't, excuse yourselves and come back another time. It's really all about the aquarium room. I don't even remember what I ate here now, and I guess I didn't think it worth taking a picture of at the time.
