Bella Pita
As a longtime resident of Westwood, I know that there's a common ailment known as Westwood Disbelief Syndrome, wherein a reveler will stumble out of a bar pretty much any time after 10 p.m., realize that absolutely nothing else is open, and freak the hell out. Yes, UCLA supposedly supports thousands upon thousands of students, and yes, it makes literally no sense that you can count on one hand the number of businesses that stay open past a toddler's bedtime, but as long as Bella Pita is open until 2 a.m. every night (and it is), you can at least relax knowing that a delicious wowshi (that's various marinated meats and cheeses baked to order into fresh pita dough and topped from a fresh fixings bar) and a side of fried cauliflower can be had, and that you can get that, with a MexiCoke, for less than a double-double with fries at the In-N-Out next door. Plus, they won't try to tell you about Jesus. Win-win!
