There are several places that do escape rooms; my favorite is Labyrinth Escapes, which is reasonably close to the venue. Ground Kontrol is a good barcade downtown, and you should definitely check out Powell’s if you’re nearby. OMSI’s a little further out, but it can be fun (unless you worked there like I did, in which case you can NEVER GO BACK).
If you find yourself with an entire extra day with nothing to do and you have a car, I would also suggest visiting the Enchanted Forest, which I once heard described as “the Uncanny Valley theme park.” It is as delightful as it is disquieting.
