Very organized. Got my first vaccine jab today - walk-in. They are accepting FOREIGNERS also for walk-in so please go asap if you're still waiting for your appointment and are looking for Pfizer in specific. It's not too crowded. The staff/frontliners/volunteers are very friendly. There are a few sections you go through before getting your jab but the process moves on smoothly and fast so you don't feel the time passing. For walk-in it takes approximately 1.5-2 hours total but there were no long queues.
