The “new” Testaccio Market opened in a modern building next to the Ex-Mattatoio (former slaughterhouse) in the summer of 2012. The space was much larger than the original market, which meant there was plenty of room to grow new businesses, especially “fast food” stalls. While dining at the market is prevalent in many cities, Rome never had such a thing before Testaccio opened stalls like Mordi e Vai (meatball sandwiches).
