Planning a trip to Switzerland?

Well I am planning a trip to Switzerland for 15 days. I have already booked my trip with HelloTravel and I wanted some first hand experience from travellers about the state. HelloTravel people have provided me a travel agent, yet I would like to know about the food habit and other cultural part of Switzerland., since first hand experience always helps.

I have consulted lonelyplanet for information, yet I would like to know more.
