I know my frickin' Asian food. Ping Gai (a.k.a. Gai Yang in Thai) is a pretty close interpretation of its Thai cousin.
Took you a little time to bring it out to your salivating customers but we forgive you. It's delicious, tender, meaty, and generously served. Try it without the lemon and sauce first to build up how you want it. Allocate about 30 minutes for the chicken to come out during weekday lunch. Not their fault though, chicken has to be charcoal grilled to get the flavour.
