I actually found out from the Champaign Taste Blog review they don't serve drinks, but they do have free miso soup with the buffet, but you have to ask them for it. I guess they don't automatically give it to people since not everyone likes it.
One other update is that they did raise the price another dollar since I went, so I think it's 11.95 for lunch (weekdays) and 16.95 for dinner. And I've been seeing a lot of varied reivews for this, but I'm telling you that it's pretty key to try and get there early in the dinner hours for the buffet...there's a difference to what's set out there early/later, especially if you want some sashimi/nigiri sushi. And take advantage of ordering rolls from the chefs as well!! All in all, I keep my rating and will have to visit again in the future.
