Travel to Gadgetzan in the Tanaris desert and speak with Dirge Quikcleave about advancing your cooking career.
I can tell by yer cooking spoon that ye know what yer doin'. Unfortunately, I can't teach ya nothin'.
Luckily fer ye, I know a guy. He's a goblin and probably the best cook on Kalimdor.
Ayep, that's the bad news, lad - ye got to travel to Kalimdor. Git to Gadgetzan and find Dirge Quikcleave. He'll set ya straight.
<Dirge spits out leather.>
<Dirge hacks loudly.>
What? I'll have you know that leather is surprisingly high in protein and low in carbohydrates, <race>.
