There are a couple of other thoughts I have.
1. If you see this as an opportunity to market your name, but, you are not in control of the base ingredients, sides etc...then you risk you reputation on their decisions of sourcing and sides. This is not always a good risk.
2. Are you doing only the cooking and none of the plating? Have you settled on who moves the meat into the kitchen? Is there a kitchen? Are you really just cooking, or will you be doing plating as well?
3. Have you really considered pricing and whether the people coming to a bar are willing to pay for food. Food in a bar is not often a profit center. Do you get cash on closing, or is this to be an account type of thing?
