Burger Dates in Portland

Being new to the area, and a cheeseburger Connoisseur, I am always hot to try the burgers of the region (Bourguignon...Burgernion).  Upon searching for datey options I came upon: The Portland Burger Blog.  I love when blogspotters get big!

THE DATE
1.  You and your date should independently review the site in advance and come together with your top three options.  Kiss it out, determine the couple favorite and head over there.
2.  Arrive at the location, ask the waiter for their most popular item and evaluate. (Low Fat Alternative: Have a salad and split the burger so you can both taste the goodness). 
3.  If you decide to do this as a regular activity, fun albeit fattening, I recommend perhaps once a week or every couple of weeks.  Keep track of your favorite. Compete. Enjoy!
