Not much to do with the Emerald Isle, but by far the best spot in town to catch live sport, especially the English Premier League, NBA and NFL. Strong selection of foreign brews and decent pub grub: fish and chips, pizzas, burgers and salads, as well as reasonable Mexican dishes. Also has a pool table and is nonsmoking.
It's located in a complex of bars and restaurants a ¥25 taxi ride from the centre.
