Dim sum here are rather cheap! Taste-wise it is pretty similar to the ones i ate in Hong Kong. I tried siew mai, har gow, char siew su, beancurd, century egg porridge, egg tarts, durian pastry puff in my two visits. And each time, i only paid US$8 for 4 plates plus a pot of tea! Excluding tips though.
Atmosphere and set-up is also the same in Hong Kong, where you have to share table with strangers unless you are able to fill up the entire table. Some customers may not be used to this culture but it really makes you feel like you are in Hong Kong as they will try to speak to you in Cantonese. You can try to converse in English or just point at the dishes you want and I think the pushcart aunties inside are quite friendly if you smile and talk nicely!
