I love the apostle Paul's example on this, aside from any serious allergies and such.

To eat what's set before us and let the gospel, blessing the people, be the point. If there's something to be offended about, let it be the cross, not the details of our diet preferences.

Food is very social, anywhere in the world.

Big difference between what I'll eat at some event and what I prepare in my own kitchen.

With ones who are more likeminded, sometimes I have them over instead of going out to eat, or offer to bring the part of the meal I'm most concerned about.
