I can only speak for myself but I've eaten at Michelin star restaurants all over the world and enjoy fine dining whenever I have the time and I love it, but sometimes I just want taco bell.
Alcohol, on the other hand; good Scotch and wine has ruined the cheap stuff for me. I can't drink cheap, or even mediocre, whisky or wine anymore. If it's not very high quality I'd rather just have something like a gin or vodka cocktail.
What's the opposite of eating the onion? I read your comment and scoffed, wondering who could actually believe this. The I saw the "Not" in the comm name.
