This is easily the most laid back capital in the world, or at least in Asia, the only traffic is from the early morning/evening rush hour and they still have a sort of curfew on the bars. We spent plenty of time dining in relative luxury in several of the French run restaurants (it seems that 60% of the expats are French in this town) and drinking cafe.
In our city tour we only visited a couple of sites, the Wat Haw Pha Kaeo with it's large number of 600 year old buddha statues and Xieng Khua (Buddha Park). The buddha park is more amusing than religious since the statues are placed all over the place without any apparent organisation or even great attention to detail. Our trip back to town was the most eventful thing since the bus picked us up "out of turn", the other drivers were really upset with him and one even blocked the road for 5 minutes whilst shouting at our driver.
We now have to leave Laos since the visa is only good for one month, after which we'd end up being fined 10 US dollars a day and probably not be allowed back in if we tried. We really recommend this country though since the people are great and always have a welcoming smile as well as a loud "sabai dee" for us.
