This is very inexpensive, simple, but flavorful and excellent Chinese food. I was initially a bit suspicious of a place with $5-10 meal options near a $50-150 restaurant, but while it is different, in its own way it is just as good -- I now happily go to both.
Standard popular-in-America options (wonton soup, various noodles), and good filling food like chicken curry; you really can't go wrong. Most dishes are $6-8 in 2017 in a city which is otherwise far more expensive. Big fan of Big Wong.
