We've been to Peter Piper Pizza and had a good time. Also, there is a place in Euless called Incredible Pizza. We've been a few times and always have a great time! They have a huge buffet, BIG gameroom, indoor putt putt and go karts, etc... My nephews 5th birthday was there and it was a huge hit. Here is their website: http://www.incrediblepizza.com/locations.php
Hope this helps. Good luck!
