It's called Petals, and it's near the Hippy Dippy Pool. I don't know if it's a "seasonal" thing, but it was only open part of the time when we were there last April. However, now that I think about it, I've heard that when Classic Concoctions (the bar inside) is open, they close down Petals. That might be what happened, because I remember seeing Classic Concoctions open at least one of the nights we were there. As for menu, it's the typical WDW bar menu, which you can find on allears.net or by looking at the menus on this site.
