Ye's is pretty much our standard place for Sushi in Waterloo. It's where we go when we're craving sushi in KW. It's all you can eat, and has a decent selection of sashimi, sushi, rolls, and other entrees. I especially love the green onion beef rolls, and the chicken and beef skewers. Plus they finally removed the limit on red tuna (my favourite sashimi).
The service is mildly horrible, which is typical for these sorts of busy all you can eat places, but I think they're substandard even considering. Extra advice: If drinking pop, get coke and NEVER GET SPRITE. If you do, when you ask for a refill the waitresses stick their noses into the cups to check if it's pop or water. Extremely rude and disgusting! They have improved on some things, eg they automatically serve you soup spoons with your miso (which is traditionally eaten without spoons but enough people must ask for it).
The food is the part that (sort of) makes up for the bad service. Like any all you can eat sushi place, they miss (ignore?) some of the ordered items. This leads to quandries where we eat all our food, order more, and then the rolls come super late, leaving us with too many rolls for too few people.
We try not to go during peak periods, when the place is packed with students, but from May to August the place is not too crowded.
At first, this Waterloo location was much better than the downtown Kitchener location in terms of roominess, cleanliness and promptness with food. Unfortunately, it eventually gave way to the strain of too many people and the service has suffered. We now go to the Kitchener-Sportsworld location instead.
