As for the nightclubs, pubs and bars. Decent as well as the not so decent. Check out this following website: http://www.vientiane4fun.com/
Girls ain't hard to locate in a number of these establishments. Most are quite easygoing, looking to know any a foreigner. But it may be a good idea to get oneself qcquinted with some of the expats and other farangs hanging out at these places before making one's move.
And yes, the law against a foreigner bedding a Lao lady exist. And there apparently have been some who were caught. Most of the time, one is let off with a payment of ~USD 500 to the police. Have also heard, most of the arrests stem from jealous boyfriends or were "setups" or because of inflexible hotel/guesthouse staff. Seems like the trick is either check oneself into a NON Government hotel/guesthouse or go to one when the occasion arises, and also don't be a miser...sometimes paying USD 4-5 or more per hotel staff at the counter not only shuts careless mouths but also have the staff bow to you like you were the Chairman of the ພັກປະຊາຊົນປະຕິວັດລາວ ala Phak Paxaxon Pativat Lao i.e. Communist Party.
Also one cannot avoid meeting tuk tuk, samlor drivers ever ready to dispense suggestions i.e. "lady, marijuana, anything?".
