Very basic menu, only a couple choices of great burgers and fries, pop or a home made milkshake which makes it simple and quick . Fast-paced atmosphere, always busy. I'll always swing by for a quick meal when in the area.
This is a quick-service restaurant that serves delicious burgers and fries. After ordering and waiting, you will be served a hamburger with freshly fried fries and a baro-gyuun patty. I think it is very good value for money. This is a hamburger restaurant only found in the western part of the United States.
Great In N Out, but they only offer outdoor seating.
This is a historic location being the 34th store and has some cool memorabilia on display by the bathrooms. Bathroom code is 1984# for the year this location opened, which I thought was a cute reminder.
Tons of parking and next to some other food options if needed.
