Reading the General Topic posts about Popeye's, Jack in the Box and In-N-Out Burger, I started to reminisce about Mos Burger -- a Japanese fast-food chain that makes great fries & burgers to order. The Spicy Mos Cheeseburger, Spicy Mos Chilidog, kinpira rice burger & fries are special faves, although I've found that in some regions they include/omit mayonnaise from the spicy burgers/dogs (but happily, all have jalapeno peppers to my knowledge!). Cheap & fresh, yum!!!
Link below has their full menu & prices, definitely worth trying if you have the chance!
