Shun Won is a very reasonably priced Cantonese restaurant with all your classic cheap Cantonese food, including some dim sum as well.
When I come here, I usually get something with Cantonese barbecue. Something like the roast pork noodles or soy chicken over rice. The congee is also pretty standard. Most dishes cost around ten dollars or less.
Overall, a great place to get cheap, decent quality Cantonese food. It is arguably one of the best places in Flushing to get Cantonese food.
