We Can't Eat Here Again

We went out with my family to a local italian restaurant. It's a very nice place, but our son seems to have some bizarre allergic reaction to the place. The second he walks in he cannot stop rubbing his nose. Then when we sit down his head starts to hurt. He gets weird and tired. He wants to lay down on the bench. This is the second time this has happened in this restaurant. We did go there another time with no issues, but we sat in a different area with no benches. Maybe it's the benches. Maybe it's the cleaners they use. Maybe it's the carpeting. Maybe...but I give up. We are not going back there.
