Yeah, it's not the best sushi in the world, but the price is right. I had the Teriyaki Chicken, salad, California Roll, and Diet Coke all for under 20 bucks, plus had leftovers for lunch the next day.
Our server was very attentive, esp with keeping my Diet Coke always full. Numerous other staff stopped by our table throughout our time there; not sure if the staff was mgmt. as they did not identify themselves. So many stopped by during our meal that it was comical....not sure if that is the standard or Yokoso was overstaffed that day and the employees were looking for something to do :)
There aren't a tremendous amount of fine dining options at the Waterfront, and most of the restaurants are national chains . I don't *think* Yokoso is a chain after a Google search, but I'm not positive. You could def do worse at the Waterfront - overall, a pleasant experience at a reasonable price point.
