The Two Peaks Mall is the local City mall. The residents, including Mordecai, Rigby, Margaret and Eileen, often come here to do shopping or to just hang out. The only stores known to be there are Icy & Hot Jewelry & Apparel, Pretzel Shack, and an unknown store that sells fountain soda (possibly a food court). It has appeared in the episodes "Muscle Woman", "Cruisin'", "Sandwich of Death" and "Ace Balthazar Lives" when Mordecai and Rigby were looking for a girl's phone number.
- It could possibly be a reference of Twin Pines Mall from the movie Back to the Future.
- Two Peaks may also be the name of the city/town that Regular Show takes place in.
- It's a reference to the surreal murder mystery show "Twin Peaks" created by Mark Frost and master director David Lynch.
