As a mother of two small children (Joe, 5 and Ty, 3), our family is always on the lookout for restaurants that accomodate kids.  Searching the internet, I found this great site that lists up a bunch of restaurants in the Houston area that offers free kids meals on particular days.  We go to Black Eyed Pea a lot and it's awesome because the menu has so many choices.  I think Denny's is also currently running free kids meals on Tuesdays and Saturdays.  Make sure to call first though, before you go!  Check out this list.  I didn't know Prince's Hamburgers did a deal for kids on Wednesdays after 4pm!
