The motif of "Hot & Groovy" that appears this time is the United States of the 1970s. It is said that it reproduces the Texas-born Mexican-style American food "Tex-Mex" that spread in the 1970s, and superimposes the image of soul music that was popular at that time.
Jalapeno is added to the main salsa, which is a typical example of Tex-Mex, for a stimulating taste. The buns are topped with corn grids made by crushing corn. "Hot & Groovy Beef" has 2 beef patties, 2 kinds of cheese and lettuce, and the chicken has crispy chicken patties, cheddar cheese and lettuce. Single item prices range from 370 yen to 410 yen each, until mid-February.
