When you click the link below you'll get an index of all the runsite directions held on the BMH3 website, in a rather unfriendly format.
The list shows the file name rather than the name of the restaurant or road. Files are generally named as follows:-
1. xxx.html for the actual directions. Restaurant names are usually prefixed "Rest".
2. xxxMap.gif for a location map.
3. xxx.gif for the streetnames in Thai.
Finding what you want might be a hit and miss affair. For example, the Delawan restaurant is not in the restaurant list but under Suksawat30.html.
Some of the directions are very old, so road layouts might be out of date. Good luck.
