I have not been to that McMenamins, but if you have never been to any McMenamin's, they are kind of fun for their quirkiness. I like to call them one of the good parts of the "keep Portland weird" vibe.

I can't speak to how the antique shopping is in Kalama, but if you want to stay some place different from most hotels, trying out a McMenamin's hotel would be a great option.
