JBX Grill was a line of fast casual restaurants introduced in 2004 by Jack in the Box Inc. JBX Grill featured high-quality, cafe-style food, avoiding most of the cheaper fast-food items typically served at Jack in the Box. The architecture and decor maintained an upbeat, positive atmosphere, and the customer service was comparable to that of most dine-in restaurants. Two Jack in the Box restaurants in San Diego, California (where Jack in the Box is headquartered) were converted to JBX Grill restaurants that were used to test the new concept. There were also New restaurants in Bakersfield, California, Boise, Idaho, and Nampa, Idaho. These stores were converted to Jack in the Box in 2006. Many features from these locations where implemented in to newer Jack in the Box locations.
