I don't know, I'm still a bit on the fence about this restaurant.
It used to be Jade Dim Sum Bakery up until about nine or so months ago. At first when Happy Dim Sum opened, the lady that used to take our orders was very friendly but now there's some new woman who (like most Mississauga joints) is quite rude; hence, no matter how reasonable the prices are, it's hard to deal with that level of customer service.
Prior to the rude woman, we went maybe once or so every two weeks for take-out. We would order rice noodles with barbeque pork - I think it was less than $2 for three pieces and it was so delicious. The steamed shrimp dumplings were a little on the pasty side but well-flavored. Very tasty spring rolls and steamed pork dumplings. Everything was always fresh but, in all our visits, we were never given chopsticks or any additional sauces but, for the money, you can't really complain. It's also cash only.
Just note that this place is not the cleanest ... think Chinatown.
