If you're willing to spend on a memorable dinner, make reservations at Barton G. The restaurant is over-the-top, but I think it's a cool evening.
Every dish is brought out as a 3D experience, as the restaurant calls it. I found this meant the dishes were made into exuberant displays with props, like the popcorn shrimp appetizer brought out in a mini, old-fashioned popcorn maker, and the jerk chicken brought out in a cage with a video screen of a dancing chicken.
I ordered the chocolate ganache, which came with a giant fake $100 bill, carried by a man in a mask who melted a gold brick shell with a blowtorch to reveal the chocolate dessert. Many of the cocktails were made with liquid nitrogen, so they were smoking when they came up to the table, which I thought added to the fun atmosphere.
