I am in the Atlanta area and is going to open my own restaurant. In order to get my name out and maybe get a couple of sponsors I have started catering.I want to also start vending at events. What lenses do I need?

Lenses or licenses? (Be sure to have a good speller check over your advertising and menus.)

Check with your town and county regarding licenses.

Do you specialize in a certain cuisine or a certain type of food, like breakfast meals or egg dishes?

You have to get a vendors permit from the city, county or municipality.
Probably a food handlers license and TaxIN number
