Another vote for Paramount.
I went to them one Saturday morning when I felt like u-no-wot. They were quick (one other patient there at the time), caring and thorough. I waited longer at CVS to pick up what they prescribed for me than the whole time at their offices.
My regular physician has an urgent care facility, too, but it is nowhere near as convenient, and when trying to use it once during a regular week day, I waited over an hour - because it was lunch hour!
Best bet, of course, is to avoid needing an Urgent Care Facility!
