My kids love to go to the Prarie Kitchen. I will admit, I'm pretty indifferent when it comes to that particular restaurant. They do have pretty good food, although nothing spectacular. It is, however, nice to go when we all want something that does taste home cooked. They have a pretty large selection of items, something for every taste preference.
One great thing about the Prarie Kitchen in Norman is that they can almost always get you in and seated quickly. There is plenty of parking space, so you don't have to walk a mile across the parking lot, reminding your kids to stay right with you! They also have plenty of seating inside. It is a really cozy, comfortable environment. The environment is really relaxed, which does make a good meal with the family a lot more comfortable.
The prices at Prarie Kitchen are a bit high, for the style of restaurant, but not so high to make me avoid it... we just don't go there every week.
All in all, I would say this restaraunt is above average, but doesn't stand out from any others.
