Great business, always open when others are not. Due to that and generally attending when the other places are shut, you will never get the same doctor. Presenting without an appointment can take a while to move from the waiting room to the doctor. Even with an appointment (during daylight hours from my experience anyway) they are usually running behind by about half an hour.
Considering they bulk bill without an extra charge for most things, and if you are happy to wait I would recommend them. All the doctors Ive seen have all been pleasant and friendly, the staff behind the counter have always been nice and friendly too. Very happy with their service.
