For those of you wondering about the antics in WC, the idea is that the servers really act like big kids: tossing straws, yelling across the room, serving up countless bottles of ketchup, making note of someone leaving to go to the restroom, getting dads to stand up and do a little song and dance number together, etc. It can be rowdy, but in a family-oriented way, naturally.
That being said, my family and I have been to WC twice in the past year and both times were left wanting in terms of service, food quality, and the rowdiness factor. I suspect most of the posters you'll find on here who have been there would disagree with me about all the above, so perhaps we've just caught the wrong servers when we went, and both times it was for dinner for those keeping score at home. Neither time was our server getting into the spirit of the place. Neither time did we get very good service (having to flag down your server for refills, undelivered food, and the check qualifies as bad service to me). And neither time did we feel the quality of food was anything more than mediocre cafeteria food (we did a la carte the first time, the all-you-care-to-eat skillet meal the second).
Still, you won't know what it's like until you try the place out. However, just be forewarned--as with any dining establishment you read about on here--that your experience will vary depending on several factors. Bon apetit!
