Rol San has a very no frills appearance, from the plastic table cloths to the big banner proclaiming "ALL DAY DIM SUM" below it's front sign, but as we all know appearances can be deceiving. I think this place serves the tastiest Chinese food I have had in the city (although to be fair, I don't eat Chinese food often so I am probably not the *best* judge). My personal favourites include the BBQ pork buns, shu mai dumplings, fried noodles with shrimp (like cantonese chow main but just with shrimp - what's not to love!!), and the spicy crispy honey ginger beef (SO flavourful).
They are open until ridiculously late - making this place a dangerous temptation for late night binges. But once in a while, it's totally worth the splurge.
