I go to City Medical Practice in Sydney City when I feel unwell as it is close to my office in City CBD, so I can pop in during lunchtime or before work. The clinic is always packed so it is advisable to book an appointment in advance. They always have a few GPs on duty so you can request for any GP with the shortest waiting time if you don't have any preference. They do bulk billing as well which is good for us. The receptionists and GPs are professional and friendly. There is also a pharmacy at the corner of the medical clinic, so it is convenient if you need to pick up any medications on the way.
