Sungshin Ironpaw stands at Halfhill Market, right across from the Halfhill flightpoint, in the Valley of the Four Winds on Pandaria's continent. A toon must be 85 or higher to start the quest for Zen Master cooking skill (525-600 skill).
Sungshin has a full set from 1 to 525 skill of pandaren dishes, most of which use ingredients sold by her. You will have to bring some fish and couple pieces of meat yourself, but by and large you can buy and cook your way to 525 without moving, since Sungshin is standing next to a cooking pot!
