NOTE - this was an onosm.org note from someone who forgot to put their proper address, thus putting the note right on the node for the city of Seattle. I've put this note right next to the current location of 2207 2nd Avenue - where a Pintxo restaurant is currently. I am not a local, I do not know if this dental business moved in, or if Pintxo was simply wrongly placed this whole time.
