Actually it was also a sitting and eating street, with lots of local food available and tables and chairs in the middle of the road, in front of a large stage where traditional performances took place.
Old and young appeared to be enjoying themselves and the food. Guest of honor was the Governor, Dr Preecha Ruangjan.
He chatted to other dignitaries, made a speech and toured one of the finest examples of a restored Sino-Portuguese home on Thalang Road, where no expense has been spared in recreating the abode of a wealthy Chinese trader.
Large motorcycle riders with some large and shiny motorcycles also gathered for the festival.
There was also a seong tau local bus, decorated with the skulls of long-dead buffalo and goats, that served local food and looked so ancient it may well predate invention of the automobile.
With trendy restaurants now opening quite frequently, Soi Romanee seems to be taking on a hip bohemian character that deserves to attract customers from among tourists and locals alike.
