Like other users mention, this place is in a strange location. Barred windows line the streets and dodgy neighborhoods encircle it, but the food is not to be missed. Not to mention the lunch special is definitely the best priced meal pound for pound in the entire city.
Unlike most American-Chinese places, you don't have to order the chicken to have a good time. Squid, fish, some weird beef intestinal lining thing, whatever; enjoy your meal and bring an empty, empty stomach.
