Hi Robert,
LindaC here.

Sorry about the link in my post. I thought I had deleted the link.

Yes, the street food business is an exciting and profitable business.
The hot dog business is a very profitable business.

Cost to put a fully loaded hot dog in the hands of a customer $0.60 sells for $3.00.
Most festivals/fairs a vendor can easily sell 100 - 150 hot dogs. Same with burgers, sausages, can drinks, and bottled water.

My Best 2 U,

LindaC
