I only went here once myself, but this place seems to attract a few regulars sitting outside on the…read morepatio of the surrounding shopping center. Most of their business is "Cafe Nashville" selling shakes, Irish coffees, and the occasional "American import" beer. For my part, I can say the Irish coffee was pretty good (the owner prepares them with Bushmills).
The inside is the "American Store" proper and they sell American fashions that look like something out of the 1950s, plus a few novelties like belt buckles, American (and Confederate) flags, and tin posters advertising stuff like Jack Daniel's.
