Volt Table 21 or Mini Bar?
I'd take a huge pass on minibar. You'll leave the meal hungry, even if it is 25-30 bites, and I generally wasn't impressed by the quality of the food. It's great, but the charm is just the "coolness" factor rather than the actual flavor.
Oh, and the service: horrible. Expect to be bumped a couple times as waiters take away dishes from the overly cramped bar stools you're sitting on.
