Grand Avenue is host to a plethora of stores, one of which is Bronstein Music, a well-known local music store that has been around since 1946.

Chestnut Avenue connects Hillside, the northern bordering street at the foot of San Bruno Mountain, to Westborough Blvd, and subsequently to one of the neighborhoods known as Westborough.
