Hodgson started his truck before being joined by three others, StrEat Mobile Bistro, UmamiMoto and Jibaro, that form a sort of core-four food trucks in Cleveland. Zydeco Bistro, out of Wadsworth, Ohio, and the truck from Cleveland's Fahrenheit restaurant round out the offerings, with Traveling Treats and Oh! Babycakes driving dessert.

But there's no innovation without growing pains, it seems, as brick-and-mortar restaurants have taken to the local press to voice concerns about their own business interests. One pizzeria claims its business is off 25 percent. But food truck crews say there's room for everyone.

Chef Oleh Holowatyj, who we spoke to in front of Dim and Den Sum as it was parked on Ninth Street Street, voiced a common refrain: "You're not going to pass up a sit-down dinner for a $7 taco."

Jeffrey Winer of StrEat credited the city council for creating opportunities for entrepreneurs when I talked to him on East 12th Street. "Councilman Cimperman, who is the councilman for downtown, has really gotten behind us. I think he really understands that food trucks aren't a danger to any restaurant. We're actually going to bring more people to the area."

At least one traditional restaurateur is hanging his hopes on Clevelanders love of eating out. Jonathon Sawyer, who already operates the wildly popular Greenhouse Tavern, will open Noodlecat this summer. The ramen-and-Japanese steamed bun house will be downtown on Euclid Avenue, a stretch known as much for empty storefronts as exciting dining.

Says Chef Sawyer about the neighborhood, "The thing that East 4th has that most other streets in Cleveland don't have is that the landlords own, from end to end on that block, every single storefront, even going [west] toward Public Square on Euclid. So we get a sense of community." He credits, as does StrEat's Winer, the work of Joe Cimperman, a city councilman that's helped the industry-on wheels or otherwise-thrive downtown.
