That's smart. Having a grill/kitchen sounds great until you actually have one. Colossal pia. Having the trucks come in is the way to go.I can't say for sure, but knowing this particular bar owner, I don't think there are any fees or kickbacks from the truck operators. He makes his money from keeping his place busy, and he understands that keeping people happy is the key to high traffic.
There is room in the building to install a small kitchen, but not enough actual dining space to make it practical to hire a dedicated cook. He feels that if he required the bartenders to do short order cooking the response time for beer and liquor sales would suffer. So, the food trucks during the tournaments are his way of solving a problem without creating another one. He's mentioned that if the food trucks work out well for the tournaments he is open to having them there for other high traffic times as well.
