TheAsphalt Café is the name of the eatery at Hollywood Arts. This is typically where most students eat lunch and buy provided food from the school. There is a indoor eatery, but, as confirmed on TheSlap, most students don't use it.
The Grub Truck is the only place to buy food, according to Festus' posts on TheSlap. Music is played overhead during lunch here, as shown in multiple episodes. It is also the usual spot for the Kick Back. Hollywood Arts' first prom (or "prome") was held here.
Scenes of The Asphalt Café are filmed in the Nickelodeon Sunset Studio parking lot.
The Kick Back is a Saturday night party at Hollywood Arts, that the teachers let the students have once a semester in the Asphalt Café. It was only seen in Cat's New Boyfriend and it is known that Tori has been there at least once.
