THAIPUAN.COM A Community Magazine
But not sure how up to date it is as it shows V Club in it's old location.
The is no soi 10 anywhere close to the north east exit of Cultural Center MRT...or none that I could find. My Bangkok CD map shows soi 10 up north of and across the road from Robinsons...ie far from soi 8...after the angled T junction.
