Chef Joseph Mahon began his career in Fullerton, was chef at renowned Bastide on Melrose Place in L.A., and comes full-circle with Burger Parlor, which takes over the Rialto Café in downtown Fullerton at night. He serves Angus beef on buns from his own recipe in provocative combinations, onion rings in a class by themselves and several Belgian ales (108 W. Wilshire Ave., Fullerton, 714.525.5111). Chef Jason Quinn, known for his Lime Truck, also offers 10 burgers and craft beers at the Playground, in Santa Ana’s new East End Promenade. Four of the burgers push the envelope—steak tartare burger, anyone?—and change weekly (220 E. 4th St., Santa Ana, 949.292.6282). The Anaheim Brewery (336 S. Anaheim Blvd., Anaheim, 714.780.1888) reopens after a 90-year break. Plans are for much-ballyhooed Umami Burger, which has five locations in Los Angeles, to open inside.
