Just from my personal standpoint, I think that 9.95 is a little too high. I mean, most people are going to eat 2 hot dogs at an event. Maybe 3 but 2 is good number. Add in a soda and chips(although I suspect you don’t do any many chip orders as hot dog orders) $8.50 retail for that. Assuming they don’t go with a water, then it would be $7.50. Your food cost profits are built into your menu prices already. So, long story I would drop the price maybe a dollar or 2. Sure, you’re gonna have the occasional person who can down like 6 dogs or something but thats only in person cutting into your profits. But hey, who am I? Not the one with the hot dog cart [:D]
I’d drop the Jones and 1/4lb. for the events and price from there. Keep a simple menu, with a lower cost.
