12) In Zurich, three triangles for the Moulangen museum (museum of wax sculptures of skin diseases). Very cool. We emailed ahead of time because it was closed to the public, and were able to pick up a key and have the place to ourselves.
13) Also in Zurich, the sustainable shopping scene is fantastic. The viaduct area RS discusses should be two triangles at least if you're into shopping.
14) I don't understand the public's love for Chateau du Chillon. It's very nice, but there are better castles out there. I'd give it two triangles. I think the history of this one is hard for myself and most Americans to care about. There's really not much context to it. The fort behind it that just opened (similar to the one in the Luzern area) is very interesting and interactive. Definitely recommend doing both.
15) The Einstein Museum (not Einstein House) in Bern is worth two triangles. I found it very compelling. Wish I had more time there, and it should be added to RS' tour.
16) If you're in Zermatt, you MUST have lunch at Paradise restaurant, below the Sunnega peak. Fantastic food, incredible views. And we saw Marmots, which RS said were a rare sight. Three triangles.
17) Zermatt town is entirely skippable. Especially if you'll be staying in the Bernese Oberland during your trip.
18) Pro-tip for Murren: If you have very limited time there, wait to be the last one to board the cable car up -- then you'll be the first one on the train from Grutschalp to Murren, which means you can be sitting on the left side of the train, for some of the best views you'll ever have on a train trip of any length.
I'm sure I'll think of more, but that's all for now!
