Far away from New York and tucked in a strip mall in suburban nevada is a pretty fantastic jewish deli. My meal "half" a reuben and some matzo ball soup were pretty great. I'm only really knocking off a star because I thought the soup was undersalted and a little oily (though other than that it's how my grandma makes it).
Don't worry that a half reuben won't satiate your rumbling belly. Their half reuben is still bigger than a whole one anywhere else. It's a pretty solid showing, though If you, like me are a fan of katz's deli sometimes you don't need a ton of cheese to make a point
