Les Houbeles
A quintessentially Czech shop right in the center: you've got to love it. How many other capital cities in the world would have a store dedicated to all things mushroom and mushroom-picking (a slightly risky national pastime---don't do it yourself without an expert present), a street or two away from the retail prime time? Les Houbeles sells mushroom-growing supplies, kitschy clothes, and, of course, the fungi themselves.
