In-N-Out Burger is a restaurant with a semi-old location that has gone through renovations, but still has a small dining area and limited parking. The service is consistently great, with cashiers replacing orders without question and offering free items for delays. The fries can be too crispy, but the burgers are often praised. Despite some small issues, such as excessive pickles, customers appreciate the generous portions and pleasant service.
