CityMD

This place is brand-new (only opened two weeks ago) and it's the best doctor's office I've ever been to. Since it's impossible to get an urgent-care appointment with my regular doctors (who didn't have anything available until June), I decided to check it out. 
It's open from 8 am - 10 pm on weekdays and 9 am - 9 pm on weekends, and takes lots of different insurance. Everyone from the receptionist to the nurses to Dr. Liu was extremely kind, helpful, professional and efficient. Plus, they let you watch TV on flatscreens in the examination rooms! If only every doctor's office in NYC could be like this...
