This place is pretty popular. Expanded to I think in the GTA region, around three stores. People at work really like to go here. it's relatively cheap and filling. Portions are pretty big, so expect to be taking home a doggie bag if you're ordering for one.
Popular items are the steamed pork dumplings and the green onion pancake. I enjoy the dan dan spicy noodle in peanut sauce and the cold spicy noodle in peanut sauce. Watch out though because their food has quite a bit of garlic. ask them to go lite on the garlic if that's not your thing.
Parking is sorta a pain in the area. There's a lot to the south of the restaurant, but you have to pay (Green P parking). There's also street parking in front of the restaurant, but remember to put money in, they patrol Yonge street pretty regularly.
The only other advice I can give, is not to feel the need to eat everything on your plate, or else you'll eat up falling asleep after your meal..
