Even though it is termed 'My Happy Feet', this massage parlour provides services beyond that of foot reflexology. Expect to also find various types of body massages on offer- hot stones, swedish, balinese etc. They even have a fish spa on site, even though being the paranoid person that I am, I personally am not a fan of this give-me-fungus exercise.
I've tried their foot massage (1 hour, $45) and it was not too bad. I liked that the therapist was sensitive to how I reacted to certain pressure points and took effort to tell me which organ in my body that point related to. As with most massage parlors, however, the therapist spoke only mandarin and I imagine this would be quite inconvenient for non-Mandarin speakers if one wants to know more about the massage. The therapist was also meticulous in ensuring that I was comfortable and that the pressure applied was not too hard. For the service and consideration its location, I would say the prices are quite reasonable.
They are usually quite empty on weekdays, and will take walk-ins if their therapists are available. However, if there is someone specific that you would like to go to, it would be prudent to first make a call to make sure that the person is not on leave (they rotate their leave schedules quite often).
