Which type of restaurant I should avoid taking infant baby to?

Upscale restaurants -- There are plenty of family-friendly joints where you can take your tot out to eat. Let the rest of us enjoy date nights, for crying out loud. (No pun intended.) That said, it's up to the restaurant to enforce its policies clearly. If it has a no-baby policy it should make that clear. It certainly shouldn't rely on other patrons being considerate because 1) many patrons aren't 2) the criteria for baby-appropriate places differ between cultures and families.
