Very nice happy hour and dinner. The hotel mngt appears to be working hard to keep the place nice. Customers need to remember it is a very old hotel so it has its quirks but we very much enjoyed our private hot springs soaks.

although it looks funky from the outside it's a really great spot- you can really feel the history of the building- built in 1914... Had a good vibe to it and I just left my door unlocked -not really worried about anybody stealing anything in a place like this- Some of the place is outdated but that is actually part of its charm Staff was very attentive in both the restaurant and in the hotel, the food was good, and I had a short but nice conversation with Gail Will be back-!
