urban cryptid: the Inexplicably Identical Mexican Restaurant
There's at least one in every north american city. All of them have nigh-identical decor and menus, right down to the drink selection and the menu's graphic design. No two of them seem to have any relation to one another. They are always among the best mexican food you can get in the cities where they're present. The chairs have handmade painted carvings of rural mexican life on the back. You've probably been to several.
Who made those unique chairs? No one knows. Maybe they made themselves. The artistry is not the best, but it has a certain charm to it.
