I think the gondolas start running at 7am or 8am (you take three to get to the top). Check and try to get up there as early as possible to enjoy better conditions. There are lockers at the second or third station (1 Swiss Franc each) but not at the very top so people changed and stored their gear before the last ride up.
On the mountain the funny thing was that many people couldn't figure out how to get back down the mountain to leave. I was asking around and no one knew so it became a joke that we were all going to get stuck up there. You actually have to go back up one of the main T-bars then over to the right about 100-150m, take another one up and then ski a long flat section until you see the station. When the clouds are really thick, it's not easy to figure out where all this is
Glad to be of help regarding the eateries. If you like drinking/clubbing, go to the basement in Grampi's. The truth is we found almost every place more expensive than I remembered from last visit to Switzerland. Maybe it's the weaker dollar or something. We just peered into the Scottish clan establishment. Lots of fried stuff and no sign of haggis, sorry to say. By the end of the trip, I couldn't stand the thought of eating more cheese or potatoes, but that place I recommended has great rösti potatoes with sausages, if that's your sort of thing. "Cardinal" beer = very good!
