For sure not baguette bar. It doesnt sound like fleshig food.
And if you are interested in a personal opinion, I think Grill King (or HotSpot) would fly with less resistance than anything with the word “bar” in it. Not sure which hechsher you will carry, but many of them will balk at putting their name on a place called a bar. (At least the ones in my immediate area.)
The real question is, how good are your fries and onion rings? And will you offer a real good garlic mayo dip?
