Reading on Gaybutton that BC Bar and Double Shot have both closed. This added to Dorothy's being up for sale and my own first hand experience suggests that JC has indeed peaked and is now on the path trod by Sunee a few years ago. With rents at about 40'000 baht a month plus add ons this is no great surprise. If DS has gone and it's one of the most popular bars then there's little hope for most of the others.
I do find it fucking tragic that landlords the world over allow greed to lead to their properties becoming wastelands.
