^with all due respect, Whataburger is sick. I had it out curiosity and thought it was gross. You want the equivalent (seriously), try Burger King. It tastes nearly the same. I dislike them both.
But if you really want DAMN GOOD burgers, try In-N-Out. That's a CA treat for you. I know these are only in CA maybe AZ and NV, but not in Texas, the Midwest, the South, the East Coast, or even the Northeast.
Also, try Tommy's Famous Chili Burgers...damn good but bad for your health. There are lots of copycats with the same name in southern Cali tho. The real ones, off the top of my head, are on Rampart Bl. (the original location in LA), Pico and Santa Monica (in Santa Monica) and a few others.
Asian food, try China town for authentic Chinese food. Very greasy, clog up your arteries, but damn good. I don't know any off top of my head. But there's this place that serves some "butter shrimp." So F'in good but full of calories and fat. I had it once, but won't return because it's good and will kill you if you eat it often enough.
There are lots of other good ethnic foods like Mediterranean, Indian, and so forth. LA is a cornucopia for delicious ethnic foods and fine *** womens...of all flavas
But a lot are stuck up and can be superficial.
Forgot, LA drivers are either horrible or inconsiderate a55holes. The Prius drivers will try to cut you off too LOL.
Hey yo, but I forgot, Smashburger is damn good. I had once in the Midwest and I hear southern Cali is going to get some soon. Try 5-guys burger as well. They're aight I thought. Also try Fatburger...Oh gosh this is turning into Food network haha.
