Hey i'm looking for a nice bar to visit in the Arlington area. Preferably with good parking and late hours!

The good news is that Crystal City is Metro-accessible.  There's a Blue/Yellow line station right in the Crystal City Underground.  The bad news is that CC is basically a work location, so it dries up at night.  About the only places I would recommend would be the Marriott Crystal Gateway or Marriott Crystal City hotel bars.  There's also a Ruth Chris Steakhouse in CC which has a decent bar.

Plan B would be somewhere in Pentagon City (one stop north on the Blue/Yellow line.  There is a Hyatt and several other bars in the Pentagon City Galleria.  If you are OK with driving or have a designated driver, there is a fairly new shopping area called "Pentagon Row" which is a restored area of shops, restaurants and bars.

Have fun!

One place that I see but haven't been in is Highline R+R at 20th and Crystal Drive, next door to McCormich & Schmick's. There's also a Bar Louie on 23rd Street.
