Came back on their 2nd round of events in the Fall. It was still very fun, actually went two weeks in a row.
At $10 cover, get there early before 9:30pm so you can wander the galleries. Now the Gem Gallery and Dinosaurs stay open until 11pm.
It's awesome to be able to get drinks upstairs and wonder about the dinosaurs of the past, except it gets crowded up there, with lots of small pockets of bottlenecks.
A fun thing to do, is make use of their Twitter/Instagram feed (tag #FNLROM) then stand at the big projection screens and watch your photos or tweets come up. Also, they have a Twitter contest everynight to win a Membership. I got a 2nd prize!!
Food doesn't really change. It was the same vendors as in the summer time.
TIPS
Worth $6 - Fidel Gastros sandwiches
Not worth $6 - Fries
Wait until almost closing and Waffles go on sale (but they aren't warm)
I'll still come back, when the theme is right :D
