How to get breakfast in Klosters a Sunday morning

As the avalanche course with Heidi Zimmermann is finished, two of us have moved to Klosters, another town 20 minutes away from Davos Dorf, as the other group (we're two groups in total) were moving into the appartment we had. So Saturday was the first day without skiing for almost 2 weeks as we spent the day wit moving our belongings (too many of them) to Klosters. Two of the others left for another destination in Switzerland (the others have to fill me in as I don't remember where they are going), and one other of my group left to visit a friend in France. We'll see each other in Canada next time I guess.
So over to how to find food in Klosters. This place is for rich ppl. Everywhere there are rich ppl and lots of restaurants, but no open grocery shops on sundays (yes Davos got open shops on Sunday), so we took the skis, went up with the gondol (Gotschna Bahn), then down a piste, then another lift, then jumping off that one again, then another lift, and then skiing down 1000 meters down to Davos Dorf. And yes after like an hour we dragged our poor hungry souls over the doorstep of a Coop shop and bought a bread and nutella-like-something. And the day could begin!
I am not satisfied with my bindings, however. The boots don't fit my feet properly, the boots are too stiff, the springs in the binding is too stiff too. And the walk-function has a tendency to kick in in the middle of a turn. So I am not sure what to do right now. THere is a boot-fitting shop in Davos with ortopeds and whatnot that really know how to adapt a boot to your foot, so I have made an appointment there, but it costs like 500 CHF easy I think. So I am wondering if I should go back to the old 75 mm system now.
Today we had a tour at the SLF (the Institue for Avalanche Research) and a guy showed us around in the labs where they work with how snow is reacting to different temperatures down to crystal level, and making models for how avalanche reacts to different landscapes and dams (the latter of interest to protect a city from avalanches as Davos was hit by avalanches in the 1950s). DAvos also got a lot of fences to protect the city from avalanches. They also make forecasts of avalanche risk from day to day. Every day there is a national bulletin and a regional bulletin coming out and this is intended for backcountry skiers/snowboarders. It is still a considerable avalanche risk at the moment in the area we are in, so we cannot ski anything steeper than 35 degrees. This goes for "Erheblich" or considerable (level 3 on the European scale). Under these conditions natural triggered avalanches can occur and also a single person can trigger an avalanche. This is due to lots of wind and wind-transported snow last week. But the danger of avalanches is decreasing in other regions of Switzerland.
Another two weeks in Switzerland before I am heading back to Norway and then Canada.
