CLOSED It's possible to make at least one statement about Porky's with confidence: The food's all right. It's not spectacular, but there are some culinary high points that make it worth a visit. While the pork cutlet sandwich is the signature dish (we'll get back to that), the two-patty cheese Twinburger may be the finest thing on offer. If you've ever wondered what a McDonald's cheeseburger might have tasted like 50 years ago, the Twinburger is your chance to find out. It's a jazzed-up look-alike down to the sesame-seed bun, thin patties, and emphasis on affable chewability over raw bulk. It's a surprisingly pleasurable experience--lowbrow, no doubt, but tasty. The fried chicken is greasier than desirable but tender and tasty. The breast pieces are a moist and flavorful delight one or two steps beyond the typical fast-food fried bird. The pork cutlet sandwich is an interesting incarnation of the Iowan classic. Pared down to the point of austere, the pork/buttered toast sandwich lacks any sort of sauce or profound spice that might pop it into the realm of flavorful. But there's a certain beauty to the laid-back combination of bread, butter, batter, and tender pork. There's no doubt that between the tasty, old-school malts, neolithic McDonald's burgers, and real (erratically) fried onion rings, a visit to Porky's is a blast from the past.
