Woohoo!
Chef Chris is the coolest guy ever.

'twas much ado about nothing, I am ecstatic to report!
He said the chef that makes the vegetarian chili at DCA gave him quite a look when Chris told him that a CM told a guest there was chicken stock in it. There is
no meat stock in the vegetarian chili.
He didn't have the ingredient lists at his fingertips, but he had talked with various chefs and it's his job to know what sorts of things they do and do not do at DLR.
They do NOT put meat stock in the vegetarian items like gumbo or chili. They do NOT put meat stock or fats into the beans or rice.
They want to please as many people at once that they can (we talked about how veggie refried beans help vegetarians, dieters, and those in various religions as well, and the omnivores generally won't really notice the difference unless they are completely used to the more traditional ways of cooking them), so when something states it is vegetarian or does not state clearly that it has meat in it (for instance, the marinara doesn't say it has meat, and it does not have meat, even though it's not called Vegetarian Marinara), it's not going to have meat in it or in the cooking process.
The fries at every restaurant are cooked entirely separately from meat items. Cross contamination, cross tastes, are both concerns. And the biggest thing he mentioned for the fries being separate from other things was the concern about
Celiac.
Ooh darn I didn't ask about the veggie burgers, but from my experience, those things are microwaved, NOT grilled, so I have never been concerned about them at all.
While chatting about all that, I mentioned our corn syrup and HFCS issues, and I think I opened his mind about those things. He said that he often just grabs an Uncrustables sandwich, thinking "hey, it's a pb&j, it's good!", but he had never read the ingredient list. But now I've let him know how junky they are...hey, maybe they'll start an anti-corn syrup revolution! Ok OK I'll let you guys have your marshmallow Tigger Tails and whatnot, just stop putting it into surprising things like ice cream, or c.s. solids into Dole Whips. And take it out of Mickey Bars, so my son can have one, darnit!
I'm thinking of a follow-up email to him, thanking him.
My mind is eased.
