Repeat after us: The best steaks in Phoenix aren't in the steakhouses. If you want a competently prepared piece of cryovac beef that looks pretty and tastes predictably acceptable, go to one of the city's many Mastro's clones. If you want to see what somebody who actually knows his way around the animal can do with a steer, go to Persepshen. Chef Jason Dwight buys whole, grass-fed, organic beef carcasses from Arizona purveyors and slowly breaks the animal down over the course of months. (His walk-in is not for the squeamish.) In addition to eliminating waste, this allows Dwight to offer a wide variety of cuts at various ages, including some smoking flat irons and giant Flintstones ribeyes aged a mind-bending 270 days (not a typo), lending them a supple texture, concentrated flavor and a hint of complex, mineral-rich funk. Dwight offers different cuts as he works his way through the animal, and the more popular ones can disappear quickly, so it's best to call and reserve. He may dress them up or dress them down, but simply presented or fancified with sauces and garnishes, the steak he serves is something special.
