We have, several times, because my DH really likes it. Me, not so much. But it's okay.
They have an allergy book. But you really need to watch. We order pulled pork and it seems like every time they bring it out with a big slab of texas toast on top, which we cannot have. We send it back and get a new one. Happens even when we tell them we don't want the toast. There seems to be a huge disconnect between the serve staff and the kitchen staff. But that's at our local restaurant. May be different somewhere else.
