After a misunderstanding with management and the bouncers, Kampai was incredibly accommodating and understanding, and so we gave it another shot.
All of the food was amazing - there was not a single dish that disappointed, but the highlights were the oysters (sooo fresh), the cauliflower, the tuna tataki, the ribs and the fried chicken.
Their pitchers of cocktails were also so yummy, pretty, and quite strong. We had the passion fruit, the peach, the moon rush colada, the Lime mojito, and the Tokyo grapefruit (which is the only one we didn't really enjoy).
All in all, the experience exceeded my expectations and really changed my view of Kampai. The only caveat I have is that the plates are small and meant to be shared, so it can get pricey pretty quickly. Otherwise, the decor was beautiful, the servers friendly and helpful, and the food just absolutely delicious.
Also, apparently Alexis Ren was there at the same time, but we didn't see her.
