Fast Food/Restaurant Chains in America - which ones are good, which ones to avoid?

[Earlybird]

Hello to all the American residents and any others who may be interested:

My questions are about eating out with children:

1. America is the country that practically invented fast food. If you are out and about with the kids and need to grab something to eat relatively quickly - where do you go? Is there vaguely healthy/appealing fast food to be had? Where do you go, and what do you order?

2. I am amazed at the number of malls/strip malls in suburban America, and many of them seem to have chain restaurants as tenants. It can be nice to see a familiar logo wherever you are so you know what you are getting, but sometimes it seems you could be interchangeably almost anywhere in America! (Hey look - a TGI Fridays!)
   What restaurant chains do you/the kids enjoy (or is that not quite the word? ) Any to avoid at all costs?

there is nothing better than a tim's coffee!! yum yum yum. I impost loads whenever I'm home!

ohhh love harvey's too

Legal Sea Foods is... mmm... [goes off into reverie] lovely....

Ooo, yes legal seafoods, in the boston area are good too. Clam chowder anyone?

Best steak house (not fast food but fab all the same) is Mortons but at $100 per person, so it should be!
