This River North multi-level watering hole (pronounced "fi-doe") means "long ago" in Gaelic, capturing the feel of a traditional Irish pub. In fact, it's almost an Irish museum, with woodwork, stone and decor brought over from the Emerald Isle. The signature brew is (surprise!) a 20-ounce pint of Guinness stout, which staffers ensure is "built," not just poured, taking up to two minutes to properly fill the glass in levels for the "perfect pour." The space itself is huge, with plenty of nooks and crannies, and the menu is fairly large as well with lineup of soups, salads, sandwiches, and traditional Irish bites. You'll find options like shepherd's pie, All-day Irish breakfasts, or Smithwick's ale-flavored beef burgers topped with Guinness mayo, pickles, onions and melted cheese.
