Startups have a vested interest in keeping you working, so traditionally even though money is tight, they tend to be well-stocked with breakfasts, lunches and dinners. Usually, it will be cereal and microwave burritos and other stuff, but it will do. Here in Silicon Valley, you can also expect a wide variety of caffeinated products. One startup exec told me that in the first month after installing an espresso machine, he made back its cost in increased productivity. If you are in a successful startup, meaning that there is actual revenue and the client base is growing rapidly, the sky is the limit. Facebook, Google, etc. provide laundry, banks, drugstores and everything else right on campus so that you never have to go home if you don't want to.
