The main draw for craft-beer fans here is the well-assembled collection of more than thirty US bottled beers, from breweries like Fish Tale, Lost Coast and Lompoc. There are also around a dozen Belgian beers by the bottle, and three or four craft beers on draft.
The main dining room is fairly huge, but there's a cozy bar area in back if you just want a beer and maybe a snack. The American-style food menu focuses on grilled meats. Most US bottled beers are priced at Y1000-1100, with Belgians a bit higher. Draft beers are just Y540 per glass during Happy Hour, which runs from 5:30-7:30pm.
Rose Hogs is one of several craft-beer dispensaries in the immediate neighborhood, along with Wagaya, My TaBReW and Basel, so Happy Hour here might be a good starting point for a neighborhood pub crawl.
