re: Is it morally wrong for me to eat at Stanley?

You can look at it two ways. One is supporting the owner and one is supporting the employees there, who still have jobs.

Tory McPhail travels all the time on food related trips. He posts about them on social media, but they're probably in the budget or it may be that the group who asked him to go on the trip pays. Whatever way it works out, it works out. Chefs do travel, but the ones who do apparently know how to make that work out.
