My friend took me to a Thai foot massage place in Hong Qiao several weeks ago. The place is part of a chain from Chong Qing, apparently pretty popular nowadays.

Their name is 重庆家富富侨足浴. The one I visited is at 仙霞路8号2楼. The normal set price is 190 CNY for 2-3 hours of foot and full body massage. They have many locations in Shanghai including one in Pudong
