Coral Level of Ala Moana Shopping Center, Honolulu, Hawaii
What it is: An incredibly upscale, hidden restaurant and "private society."
Why it's cool: Vintage Cave opened in 2012 poised to be a "private society elevating art, culture, and pleasure." One of the most exclusive, and elusive, restaurants in Hawaii, Vintage Cave offers 13- to 15-course prix fixe menus for almost $300 a person, not including wine (and with a wine cellar as vast as Vintage Cave's, skipping the wine is not recommended). Diners can admire the private art collection, including expensive Harry Winston jewels and Picasso drawings, around the sumptuous meal prepared by former French Laundry chefs.
