Ed Shevenell, 27, gets a lot of smiles when he crosses the Casco Bay Bridge in his 1961 Cushman truckster with the steamer on the back.

“The fastest it goes is 42, so the South Portland bridge is kind of my max,” he said.

Shevenell and his partner, 26-year-old Kari Williams, live in South Portland but spend most days on the Eastern Prom selling, as Shevenell puts it, “cleverly named dogs with mild to wild toppings.”

Their newest item is “The Grange,” a hot dog topped with B&M baked beans, caramelized onions and sriracha ketchup – designed to give Mainers flashbacks to childhood bean suppers.

WHAT THEY SELL: Two types of dogs – a Pearl all-beef dog with natural casing and a Jordan’s red snapper – with creative toppings. The “Don’t You Forget a Banh Mi,” named after the Simple Minds song, is topped with banh mi slaw, hoisin mayo and lime juice.

HOW MUCH: $3 for plain dog with standard condiments; $5 for specialty dogs.

CUSTOMER FAVORITE: The Born to Brie Wild, topped with brie, apricot preserves and spicy brown mustard. “We grill the bun with the brie in it, so it gets all nice and melted,” Shevenell said.

HOW TO FIND THEM: During the week, the couple sets up on the Eastern Prom from 11 a.m. to 4 or 5 p.m. ­– later, if the weather is nice. On weekends, they do special events and pop-ups at local breweries. Check Facebook.
