Riverside is not a neighborhood but a street. However, it is emerging as its own location. It goes from Shelby Park through all of East Nashville, and has a grassy median and bike lane much of the way. It mostly runs parallel to Gallatin without all the traffic lights. Two intersections have recently become local favorites with offerings such as Mitchell’s Deli (and coffee shop), the Pied Piper Eatery, a beer garden, pharmacy, and pizzeria that have made the houses around them quite the hot properties.
