Mayor Palmer DePaulis formally inaugurates street vending in Salt Lake City Wednesday by biting into a hotdog with the works along South Temple near State Street. Hundreds of vendors plan to set up shop around downtown and Sugar House in the next few weeks. City officials say the vendors, selling everything from food to flowers and balloons, will set up their carts for business gradually as they obtain health department approval. How much will a street-side lunch cost? The least expensive items on the menu of this cart, owned by Art Carlson, are a beef polish and a quarter-pound dog, each selling for $1.60, including tax. When not in use, the carts will be towed to commissaries that meet health department regulations.
