Beer Boy is the first craft-beer izakaya from the popular Craft Beer Market chain. The beer list is focused on "rare and extreme" craft beers, mostly from Japan but with a few US brews as well. The food menu is a mix of izakaya standards - grilled chicken, potato salad - and beer-friendly dishes like lamb kebabs and smoked oysters.
As with the CBM branches around town, the food is a cut above average, and even the simplest dishes have a distinctive touch. The very appetizing lamb kebabs have a definite Mediterranean flavor, but they're served like Japanese-style tsukune, with raw egg for dipping. Spaetzle salad - something you don't see every day - has a cheesy base (like a German mac 'n' cheese) but with a bit of truffle flavoring, and it's topped with carmelized onions.
Some other highlights include grilled scamorza cheese wrapped in pork, excellent grilled bacon, and well-executed yakitori and grilled vegetables. The nine craft beers on draft are at least a bit more rare and/or extreme than average, with frequent tap takeovers and other special offerings. They're priced the same as at CBM branches - Y480 for small-size glasses and Y780 for medium. You can also choose from a few different wines and some unusual sherbet-like shochu cocktails.
The brightly lit dining area is fairly typical of budget izakayas, with seating on stools around large tables, but the counter area is quite comfortable. Budget around Y2000-3000 for food and drink at dinnertime.
