Short version: For the price, VIP is great. The food is good for this price range, but don't expect 5-star quality food. You'll feel better spending $10-15 on decent sushi here rather than spending $40-50 on great sushi at Morimoto.
VIP is a cross between a night club and restaurant, but don't let the dark lighting turn you off. Monday-Wednesday is the time to come if you like sushi, as a selection of rolls are discounted to just $2-4 each. They also have lunch specials on the Chinese menu every day.
The food is all pretty good but nothing to write home about. However, the great prices for decent sushi keep me coming back again and again.
