Just as an example: I paid CHF 25 today for a simple lunch (2 meals, 2 drinks). It was a mix of healthy and not so healthy food. As already mentioned, supermarkets offer a lot of choice and you can spend less than that on lunch there.
The Swiss Coupon Pass is definitely worth it, if, as you said, plan accordingly. You can save a lot if you use just a few coupons. It's a new product, so there won't be many people who have used it yet. Please see here for details, and how to win a hotel voucher if you buy one: myswissalps.com/ swisscouponpass.
I would not recommend to withdraw your whole vacation budget from an ATM upon arrival. Don't carry more than you can afford to lose. Most shops, hotels and restaurants accept a wide range of credit and debit cards. My experience is that debit cards are easier and cheaper to use than credit cards, but you would need to check with your bank to be sure. Having some cash available just in case.
Enjoy your stay!
