Native Guatemalan Erwin Ovalle opened Ovalle’s Mexican Café a few months ago in St. Elmo, fulfilling a dream of opening his own traditional Mexican bakery and café. After spending time in Mexico during college, he fell in love with its rich street food scene and decided to bring those flavors to Chattanooga. Last Thursday, I had an itch for some Mexican food, so I wanted to see what Ovalle’s had to offer.
