I can only remember just a few of the bar names in Soi Seaperl, I have been thinking of creating a soi map for that soi for long time but never did.
Soi Seaperl is created on public land, isn't strange that somebody can make business and sell leases of the land without owning it?
The contracts is usually running for only one year, maybe because of the point above, and if a hotel want to buy the land one day, the bars will be wiped out very quick.
Soi seaperl look nice and is worth a visit, but I wouldn't buy a bar in that area.
