Popular for their dumplings and Northern Chinese dishes if you are around the area but probably not worth a detour.
You can expect several things here: relatively consistent quality, authentic northern Chinese flavours and a reasonably priced menu. So this is a good option if you are ever out of ideas of what you want to eat that day and want a no frills go to place with a ton of choices.
The dumpling skins are made in house and therefore understandably thicker than other dumplings that you may be used to. Some people like it and some don't (myself included!) so I think it just depends on your preference.
If you are going for the dumplings I recommend trying the pork with fennel (ie. dill). I have grandparents with northern background so I've been eating dumplings since I was 2 and have never tried having dill in dumplings before.. And it was surprisingly good! Interesting flavours that is unlike the combo with chives or cabbage.
3 stars overall may mean I am too spoiled by all the scrumptious Chinese food around Richmond Hill.. So I think it's definitely worth checking out if you manage your expectations and you may end up finding yourself a new go to resto.
