I am an avid cook and purchased (in US) a small Cuisinart propane grill for portable grilling at the Wiese River, etc.
Unfortunately, I have not found the 14 or 16 oz threaded propane cylinders (eg Coleman style canisters) to make my grill functional for its intended use! Nor have I been able to ship such cylinders into Switzerland using trusty Amazon.
Buy a cheap BBQ that takes charcoal. Buy charcoal. Grill. Think "wow, this really does taste better!". Enjoy the smell of smoke in your clothes for the rest of the day, to remind you what a beautiful BBQ you had.
I know that you asked for 'A' and I'm going to do a typical forum thing and ignore 'A' while telling you that 'B' is better....
But for grilling-on-the-go, you might consider using charcoal and one of the many available public BBQs. Most parks / hiking trails / etc have designated spots where you can use the BBQ on a first-come, first-serve basis.
So it doesn't really answer your question, but hopefully it helps you get started.
For the small propane bottles, I think I would take your existing propane bottle into a camping shop and see if there's a camping fuel that might be compatible? Otherwise, your best bet will be to buy something like this adapter , modify it to fit a Swiss propane canister, and use that. Assuming you're talking about one of the Cuisinart grills that are bigger, I guess you're transporting it by car rather than on your back, so you should be able to accomodate a 5kg propane tank as well.

LOL, Loved your lead-in sentence!
This is about portability, as in strapped to my bicycle.
As you're in the Basel area, you might try nipping over the border and seeing whether there's some way to make Camping Gaz work. It's available at the Decathalon in Mulhouse, among other places.
Do a google and you'll find some info about adapting it to work with various size fittings. I gather it doesn't fit UK-style adapters, but most UK campers find that with some jiggery-pokery, they can make it work. You might be able to do something similar.
