JBX…no it’s not the code for an obscure airport. It’s the name for the new “fast-casual” restaurants taking over certain Jack in the Box locations. Sitting somewhere between greasy fast food joints and full-service casual restaurants, JBX locations serve a fancier menu (chicken-avocado club sandwich) with a healthier image. Prices are higher than you’d spend for a burger and fries, but, hey, you get a choice of six dipping sauces. The decor is likened to that of Starbucks. Already open in San Diego, the company announced last month that it will be expanding JBX into Boise, Idaho and Dallas. Here are menu scans and photo links from a San Diego blog. Other fast food chains are propping up the higher end of their menus with Angus beef burgers at Hardee’s and fancy salads at Wendy’s.
