One of the highlights at Tokyo's only Okinawan Mexican restaurant is the spareribs made from heirloom Okinawan pork, which you can order in advance when you make your reservations. The menu is generally split between Mexican and Tex-Mex dishes (burritos, tostadas) and Okinawan fare, with some nice surprises like Mexican Day of the Dead craft beers. Budget around Y3500 for dinner and drinks. Burritos are also available for take-out.
