I've heard stories, don't know if they're true, that Einstein kept a closet full of identical dark suits. One less choice he had to make when he got dressed for work. The cafe that bares his name takes the same approach with their meals. Everything I ate in Cafe Einstein tasted the same - like nothing.
Everything, that is, except the beer. The beer was quite nice and made for a happy diner, food notwithstanding. My German friends make some damned good beer.
