Had dinner again here this evening. Food was as good as before although the service was a bit on the slow side. One tip: when you order something, make sure you specify a quantity. For example, I ordered "Wasabi Mussels", which is an appetizer. Note the plural form of the dish, which is also on their menu. I received exactly one Wasabi Mussel. Ditto for sushi--make sure you specify a quantity or you will receive just one piece of whatever you order. No big deal but it's good to know going in.
The sushi was good and fresh, as was the sashimi. I also ordered a couple of their rolls and garlic beef from their "kitchen" menu. I finished with a scoop of mango ice cream.
One small nit: their menu states $21.95 during the week, and yet my bill came to $27. I'm not sure if the difference was tax (beverage was supposed to be included in the price), but that was a bit of a surprise. I'm not from the area so maybe that's the normal amount of tax.
I'll definitely be back on my next trip to Markham.
