The Saturday Market (also happening on Sundays) is an interesting way to spend some time and get a feel for Portland. It's literally right on the Skidmore stop for the Red/Blue line so easy to get to/from. Right on the Willamette River also. Many of the craft vendors are quirky in the Portland manner but fun nonetheless. Some good to very good food vendors. Even a couple of craft beer vendors so you can stroll with a beer (within certain limits).
