Here's a good example of a restaurant where one should not bring a baby or toddler:

I think there are very few places that I would not bring my daughter, but Alinea is one of them. Every parent needs to have an exit strategy if behavior starts to break down. For us, that usually means going early and ordering one course rather than three, and making sure one of us is prepared to bail with our daughter if she starts creating a problem. That doesn't work at a multi-hour experience like Alinea.
