Sam's Beer Store is also known as Mitsuya Liquors. I'll provide an address and directions soon, as all of my readers who are located in Tokyo will want to make for it with the quickness.
I rated both the Cave Creek Chili Beer and the Taybeh Golden 2.3 out of 5, but for very different reasons. You may be able to see the details at ratebeer.com without logging in, but the gist of it is that the Chili Beer was not beer as much as Picante Salsa without the chunks, very interesting but without any beerlike redeeming qualities, while the Taybeh was a perfect copy of a German pale lager, except minus any especially good taste. It reminded me of the worst Bulgarian beers, which is no insult. I certainly believe the superlative on the label: "The best beer in the Middle East".
But give me a Kamenitsa or a Zagorka any day. :)
