I've been to Gatlinburg and New Orleans but had Bubba Gump in Vegas. It was ok. I thought the decor was very well done and the Run and Stop signs work really well.
The food wasn't anything spectacular, but my boyfriend's food was better than my choice. Process are decent and service was good. Our waitress came over and gave us some Forrest Gump trivia questions, which we got all right. I thought we were going to win something though, lol.
I wouldn't make any special trips back to BG, but I wouldn't oppose to going of anyone wanted to try it.
