Quoted from romulusx:
At the very least have cold beer vendors on the floor and lunch trucks outside.
I'm guessing food trucks would be difficult if not impossible due to all the restaurants in the hotel and adjoining parking lot.
As much as I love the idea of food trucks, that one-niche industry is oversaturated. Quality has suffered now that every schmuck has a truck. Brewery tap rooms around the Chicago 'burbs often have them on site; nothing to write home about. All the truck food I tried at TPF ranged from mediocre to ice cold.
