We don't go often, but I like Arby's and just eat a regular roast beef sandwich with BBQ sauce and "horsey sauce" on it.
I was also surprised by the idea that they don't have any in Seattle. I think of Seattle as an area - more than just downtown. There are a ton of Arby's in the area. I think of Arby's like a McDonalds, etc. - convenient for road trips, not someplace you'd go for an everyday meal. They are commonly located at freeway interchanges, etc. The one I go to most often is at a truck stop half way between my home and my parent's home.
