Plenty of room. That’s what you’ll say about the Model 510 Sidewalker hot dog cart. With a spacious steam table and two condiment pots, you can serve up hot, delicious dogs all day. And with a urethane-insulated beverage area that holds up to 135 cans, the Sidewalker 510 keeps your drinks cold with few ice changes. The 510 is called The Sidewalker for good reason. It’s a push-able hot dog cart designed for the sidewalks. Unlike the 525, the 510 doesn’t have the bulky trailer attachments. It’s designed to be pushed to its destination.
