The main activity is wandering the Night Market, which is really just a more toned-down version of the raucous Night Bazaar in Chiang Mai. Like its big-city model, you can find a few bars and clubs (a bit seedy but fun). In Chiang Rai, there are the standard "beer bar" storefronts with such names as Cat Bar, Lobo, and Butterfly lining Jed Yod Road, which runs parallel to Phaholyothin Road a block to the west.
