i think the reason for the 5 guys liking is a matter of convenience. in my case, arlington is a pita to get to from work or home. you are only allowed a short distance out of our first due area in NW, so we have two 5 guys, dupont circle and irving st. plus they give a good firefighter/paramedic discount, hence you may say, a little bit bias'ed. even at home 5 guys is on my doorstep. maybe one day Ray's...one day.
