"It's the first one in America," says Alexander Hiller, Director of 100 Montaditos, which just opened this past Friday in midtown Miami (just across from Hurricane Grill & Wings). There are some 200 locations worldwide (in France, Mexico, Portugal, and, mostly, in hometown Spain), so these are no rookie operators. Think of it as The Dollar Store of fast food franchises, although admittedly I've never seen Serrano ham in a Dollar Store. 100 Montaditos serves up plenty of Serrano ham, thin wisps of the precious pork placed in warm, crunchy-crusted, olive oil-drizzled, fresh-from-the-oven bread (the par-baked sort imported from Spain). That's your dollar sandwich right there, which ain't bad.
