I have to give a +1 for Maki. I like Hockey Sushi too but I don't like their spicy salmon which is my fave sushi. Right now, I'm having a love affair with Akabane on Bayview at High Tech Rd. Really good and fresh and great variety. Service is awesome and the prices are comparable. If you go, try the deep fried corn cakes.
As a Thornhill resident myself, I have been going to Hockey Sushi for years. Though not very consistent with service (as all sushi places), the price point and menu hits the spot for me. It is located at Centre st. and New Westminster Dr.: Weeknight prices are $17.99 and Weekend at $19.99. This includes pop! Was just there last night!
You can't expect too much from AYCE - you really just go for mounds of food, and hope that things come out hot to order and things are not missed. I found yesterday's meal to be quite adequate for what it serves - food came out relatively quickly, hot, not loaded with rice, and the wasabi seemed 'fresh'.
As for Richmond Hill - I can't give you too much of an opinion as I haven't been there for AYCE in years!
