Sushi Station is a good place to go for some quick sushi, especially if you have the kids with you. Prices are very reasonable and the food is good. Not a "gourmet" type of sushi bar, but they have all the basic dishes you usually encounter. If you don't see a baked scallop roll on the conveyor, just ask your server and they'll bring you one - they are yummy.
The bill for us with the kids usually ranges from 40-60 bucks, which isn't bad at all for what you get. Service us slow when they are busy and the conveyor gets empty fast. But, be patient or just ask your server for a dish and they'll get it for you!
