To whoever it was that did the lovely job cleaning up and reformatting this page this morning. The wiki is still set up to allow anonymous editing - we get very little abuse (and I usually fix it pretty quickly), but I'd love to know who did this nice job cleaning up.
Also, obviously, I've just added this comments section to this page. Restaurants, especially, seem like they'd be a fertile area for discussion and I'd like to encourage it to take place in the comments system here.
That all said, I really miss Toraya and Blue Ribbon since I no longer live right near them. I hope you all are visiting them and supporting Arlington's wonderful local restaurants!
