Definitely the one with the bar in Star Wars - Endor? I forget which one...just the bar really...not the one with Soylent Green (oh, wait a minute, that's Earth! ;)
In Return of the Jedi they go to the Forest Moon of Endor (I think the planet itself is uninhabitable). It does look pretty too. I'd be wary of the ewoks though.
Oh, the one with the bar in the first movie is Tatooine, the desert planet. Looks hot. Interesting bar though. There's a cool bar in The Force Awakens too, inside a castle. I can't remember what that place is called.
