We went by County Cork the other night, and happened upon their happy hour (4-6pm). The menu is all about food, ranging from $2-$4.50. The HH menu includes a burger, BLT, scotch egg, banger and mash, fish-n-chips, plain ole chips, wraps, and a fish sandwich. Be forewarned, the tables are sticky—it used to be that the tables were covered by plexiglass, but now the tables and their sticky paint is exposed, and well, sticky. The food was by and large good, not exceptional, with the exception of the scotch egg which had the life cooked out of it (I guess that'll learn me about ordering a scotch egg at an Irish tavern). And a hamburger, banger & mash, scotch egg, and two pints were $17.50—pretty exceptional, really.
And if you're going for beer, particularly Irish beer, the County Cork can be pretty good. Compare Beamish, Guinness & Murphy's for example. Of their 20 taps and several cask engines, there's most always a cider, a couple lagers (Harp & Miller), and generally a broad selection of beers, some familiar, some less so.
