Break out your green shirt and your shamrock shades for an epic day of drinking in the best bars in Houston. When you join this pub crawl you'll get a list of participating bars -- everything from action-filled sports pubs to relaxed wine bars -- a map to each location and the exclusive drink specials at each one. Then you can chart your course for an amazing day of green beers, Irish whiskey and plenty more. And when the day is done? Do it all over again tomorrow -- your 3-day pass lets the St. Paddy's fun keep going for two more days!
