I am looking for information on how restaurants (such as Pappasito's and Monterey's Little Mexico) attract customers.
For instance, what cultures, attitudes, structures, and values cause customers to gravitate toward those restaurants.

Start with the Library's Marketing Guide: http://library.uhd.edu/marketing
There a few different databases you can try. Business Source Complete and ABI/Inform are two of the best resources for business research. Also, you might want to try PsycINFO since why people choose places to eat/shop has a psychological element to it.
Try searching terms such as:
“restaurants” AND “consumer behavior”
“food service” AND “marketing”
“restaurant” and “marketing”
"food service" AND "consumer behavior"
