This medical centre is very convenient due to it's extended opening hours, along with the location of a pharmacy in the same complex.
I've noticed some comments here complaining about a long wait - this is a walk-in medical centre. There are NO appointments made. At times when there are many doctors attending you will be seen more quickly than at times when there are only 2 doctors on - so you're best to ring ahead and find out what the wait time estimate is (they will tell you roughly how many patients and help you guess the wait time). Just avoid the super busy time if you can.
One thing I have noticed, however, is that although there are a lot of good receptionists, there is one who, will barely acknowledge some patients (this is really uncomfortable to watch! she is so rude), and for other patients (perhaps people she knows,) she becomes animated and friendly and kind of disturbingly obsequious. This is a problem because I don't believe it's ethical for a sick person to have the added irritation
Anyway, on the whole, there are some great doctors and some average doctors. I would recommend this surgery overall because of its convenient hours/
