Most of my meals on a bike tour are in a campsite, so for me the cook kit and stove is a must. I used to mostly rely on liquid fuel stoves, but for bike tours I am slowly switching to butane mix type stoves. If I need more fuel, liquid fuel is typically sold in gallon cans, I would much rather buy only the amount I need in the smaller butane canisters. And to make things a little heavier, I am using my old stainless pots more and titanium cooking pot less for bike tours. The titanium is being saved for backpacking trips where weight is more important.
That said, where I can get a good restaurant meal, I certainly take advantage of that.
Stove fuel, depending on type of trip or type of stove, I plan on 35 to 55 grams of fuel per day per person. (That is fuel only, not weight of containers.) But more restaurant meals means less fuel use.
