I think the best are ones that fir the story well. Multiple rooms is always important, because if not you get bored of the main room after an hour and it feels like you're ending on a lull. It's best to have a small room at the end that's all new, so people get a rush. Some things I've seen that are memorable are the ones that use senses you're not expecting. Ordering jars by smell, for example. Or shooting something with a dart... anything physical like that. I've seen some cool things with projectors, with actors, and more.
