Food was good. Pizza and mashed potatoes especially so. Overpriced, but not terribly so for WDW.
Service was mostly bad. Ate at the one on West Side twice, first time was fine. Second time we walked out, as they kept giving our food away to people who came in after us, despite my calling attention to it, and us standing right there at the end of the order que.
So, we still liked the food, and started going to the one at Marketplace. First time, food was great, service good, etc... Second time, order was wrong, had to send it back, waited 10 minutes for 1/2 the order to be corrected. Third time, they lost our order completely. After over 25 minutes of the pager not going off, and people who came in well after we ordered were sitting down and eating their food, we checked on why. Our order was nowhere to be found. They had completely lost it. Instead of waiting another 10-15 minutes more for the food, we got our money back and went to the Earl next door.
That is our experience with WPE.
