Happy hour revelers in the market for a mega-libation will enjoy this hotel bar's Very Big Cocktails -- cosmos, margaritas and other drinks served in a 48-ounce martini glass. Order Guinness, Blue Moon and four other draft beers in 16-, 22- or 34-ounce servings at the eatery's 160-foot-long bar, which is the longest free-standing bar in North America. Grabbing a drink with a group? Big Bar also offers an 106-ounce glass table tap to share. Pub grub includes a shrimp cocktail, cheese quesadillas and thin-crust pizza. If the bottle-lined windows offering a view of Tribune Tower and other downtown landmarks don't provide enough to look at, the bar also features several TVs -- including two 103-inch plasma screens -- broadcasting sports, news and other programs.
