Angelenos are spoiled for choice when it comes to roast chicken, from the smoky Peruvian-style chickens at Lola's or Pollos a la Brasa to the garlicky Armenian birds at Marouch and Carousel, the soft, savory hens at Brentwood's Reddi-Chik to the oregano-kissed chicken at Papa Cristo's in the Byzantine-Latino district. Nowhere else that I know of can you duck into a place like Zankou and walk away with a fragrant rotisserie chicken in about the time, and for about the price, of a soul-killing meal at Burger King. Still, even among the feathered plenty, the chickens at Grill Masters stands a cluck or two above the rest: extravagantly seasoned fowl cooked on rotating spits, perfumed with smoke, slow-roasted and glistening with juice, basted in its own fat plus probably a dozen other things, soft enough to eat with a spoon. And the skin! Like a thin sheet of crackly caramel, salty and drippy and saturated with herbs, chewy but taut and crisp enough to give way under your teeth with a magnificent thwack. But find a tree to eat under — the hot, succulent bird does not travel well. Grill Masters bright red catering wagons fold out like Mr. Haney's truck at local farmers markets, including the Tuesday Manhattan Beach market, the Wednesday noon downtown market, the Thursday South Pasadena market and the Sunday market on Larchmont.
