@dagmaraka,
Choices vary but I see most of your points to some extent, dag re priorities, robert re time, and both, re "value". In contrast to lightwizard, whom I don't believe just this once, I know many restaurants, even in this pretty tunneled city re food, that I get a kick out of for their savvy on flavors or - sometimes more interesting to me - procedure. For example, a local restaurant here, Vivace, which I'd never name as some top international place, showed me that parsnips can be fantastic.
News for a girl who thought parsnips were slime. That in itself is worth time and money, the knowledge growth being part of value. (And that entree, which I won't go on about, didn't cost all that much anyway.)
So - what does cheap mean? usually it's about money straight up, but can be time as money, about effort as a kind of money, and new knowledge which can be translated to grocery store purchasing.. as value.
