I've been to 168 Sushi Japan Buffet in Brampton and Mississauga. Both restaurants are usually pretty packed.
My overall experience is it's not worth the price, you're better off heading to Heart Sushi in Hearthland or even Daikon on Winston Churchill, close by.
The kalbi was great but inconsistent. The fish is hardly there in the rolls. I don't understand why a place would charge you $30 and then not give you what you've paid for. The food was OK, nothing stood out. It was a mediocre experience.
