Macau Culture

While in Macau I visited a fish spa. Although new to Macau, this spa was very unique and something I have never heard of before. My pedicure was performed by tiny fish that nibbled on the dry skin of my feet while soaking them. The purpose of the spa was to remove the skin and increase the circulation; glad they didn’t have any leeches there also.  It tickled and throughout the rest of the day I felt like my feet were prickly. Do you think that is a good thing?
