I like em anyway I can get them. From a business standpoint though it changes. Boiled dogs are faster, you can boil a large amount in a small amount of time. Flat grilling I am not sure about. I love them that way. As far as a flat grill for the cart what type of a grill are you looking at, BTU’s?, is it covered? I am just curious. I wouldlove to grill mine, but I also have volume to think about. Can you recommend a grill?
