I had been to Switzerland for three weeks, and the cost of living, I experienced, is very high. As my brother is currently staying there, basic food and accommodation wasnt much of a problem, but other things were a problem.
1. Food outside can cost approx 12 to 20 CHF per meal (full).
2. Public Transportation is also very expensive, and I was surprised by this, since I feel that if it is so expensive, then why not people use their own cars. The only plus point that I found out was that trains are really fast, warm (outside it is cold; to some extent, atleast), punctual, frequent (depending on place of travel), and you always get a seat (unlike in India, where getting a seat is rare).
3. Groceries are comparatively expensive, but in Coops and Migros, they are cheaper.

Overall, I liked the country, and plan to visit more often in future, maybe 15 days a year. But I may not be lucky every time as far as basic food and accommodation is concerned. My expenses were approx 1000 chf for 15 days exclusive of food/accommodation.

My question is, if I carry 2000 CHF for 15 days, would it be sufficient to survive in Switzerland for that period, (if I have to pay for my own decent food and accommodation).
