I don't know how long it's been open, but I noticed the other day that there is now a Matt's Hotdogs (formerly Matt's Famous Chili Dogs) in the Totem Lake West mall in Kirkland. That mall doesn't get a lot of traffic, so hopefully they'll get enough business to stay. It's located at the east end of the mall, across the street from Mcdonald's and Taco Time. I had two chili dogs just the other day. Yum!
