Nope. If you’re allergic to certain foods, it’s up to the restaurant people to deal with. If they can’t help you, they’ll tell you up front. For example, a Cracker Barrel Restaurant manager explained to me that wheat flour is actually in the air, because they use so much of it. If you’re a celiac, you don’t want to eat there.
And of course, I assume that if you’re extremely sensitive, you don’t even want to go inside.
