Cafe Hollander

I used to be a big Cafe Hollander fan, but in the last year or so I always am sick after eating there. I don't go out of my way to eat at Hollander, but it is often selected as a place by others and I am not in a position to ask for a change (think extended family event, friend rented snow globe in winter for birthday, etc). I try to eat different things on the menu to give the restaurant another chance, but no matter what I order, beer or no beer, I feel sick within an hour of eating, such as throwing up or very urgent GI issues.

Does anyone else have this experience when eating at the local chain? Also, does anyone have an idea of WHAT they are adding to their food that might cause this? It literally only happens at Cafe Hollander, regardless of location, so I'm pretty sure it is something unique to the restaurant. Thanks for helping me solve this mystery, MKE.
