I am an absolute burger fanatic! I wanted to know, who serves the best burgers, in your opinion, in Ashburn? My favorite in Ashburn might be 5 Guys, even though they serve up those little greasy "griddle" disks. Somehow they are really great and man are they tasty! They make it all work! My favorite overall burgers are the jobbies that the Palm makes for lunch in Tysons. They used to be about $12 (ouch!) when I worked down there! Another spot for greasy "flat griddle" burgers is East Potomac GC (Haines Point). Get the double and you will be full!
