Is it OK to make an ADR if you have no intention of eating a meal? I've always wanted to check out the Sci-Fi but never really wanted to eat a full meal there. Last year I tried to do a walk up, but the wait was more than 2 hours. I think it would be a good spot to have a little milk shake break, but not if I'm going to get a lot of flack for taking up someone else's spot.
