Think of the arepa as a grilled cheese sandwich made with two fluffy corn cakes, but toss in an angelic choir singing "hallelujah" as your mouth and belly radiate a warm, happy glow. That's the arepa at Zaguan: fat, fluffy corn tortillas with kernels of sweet corn, gobs of oily cheese and, if you like, a pile of flavorful ham or shredded chicken or beef. Dump salsa all over the top of the arepa and get messy, or apply after each bite. It makes for a great lunch so long as you can resist the impulse to curl up under your desk for some postprandial hibernation.
