So, my favorite is In 'n Out Burger. They wisely stick to a limited menu of burgers, fries and drinks. Their Double-Double (two patties with cheese and onions) is tops.
IN-N-OUT's Double-Double is fantastic. I usually get it Animal Style (extra sauce, extra grilled onions, pickles). IN-N-OUT also has a (not so) secret menu for those who want something a little different.
FIVE GUYS burgers are the best I've had...
They're opening one around the corner from my apartment. They'll be opening in about two weeks. I can't wait!
