Granted, we've only been once and it's been a while, but the only place we absolutely hated was Bongos. /shudder
To give some perspective, though, here's what I've found from this thread:
These places were mentioned multiple times:
Rainforest Cafe (10 times)

These were only mentioned once: CRT Dinner, Lotus Blossom, Biergarten, Boatwrights, Pizza Planet, The Plaza, Cape May, Yak & Yeti, Chefs de France, Coral Reef, Boulangerie in France, Sunshine Seasons, Captain Cooks, Marrakesh, Tomorrowland Terrace Noodle Station, 50s Prime Time, Riverside Mill, Spirit of Aloha, Cyrstal Palace, Tony's Town Hall, WCC, Flame Tree BBQ, and Hoop de Doo.
My apologies if I didn't match up some of those abbreviations with some that were already mentioned.
Bottom Line: Avoid Rainforst Cafe. Think twice about Sci Fi, ABC Comm, and Rose & Crown. But for every bad review you see of most things, there's at least one good review out there. EVERYone had different tastes and experiences and there's no telling what your wait staff will be like that day or what your own personal tastes are, so in th eend, if you think you might like it, try it out. It won't kill you if it's bad.
