I often spend far more on a home-cooked dinner than eating out, due to finding amazing ingredients I want to try, such as an expensive imported cheese that goes well with an artisan chutney and then you need a good wine with that.. I wouldn't try these foods outside of an expensive restaurant, which I only go to rarely in anycase. The best cuts of fish or red meat will put you back a little also, though it's worth it certainly when you have guests, for the flavour quality. But certainly, I would say it's less expensive to eat well at home.
