Pandaren Xpress

Pandaren Xpress was a fictional food-delivery service integrated into World of Warcraft announced by Blizzard on April 1st, 2005. It was a parody of a real life business deal between Everquest II and Pizza Hut, in which typing "/pizza" from within EQ2 allowed players to order pizza from the comfort of their gaming chair. The name chosen here is probably a reference to Panda Express, a real restaurant chain operating in the United States. The character featured in the screenshots, "Yann", is a reference to famous chef Martin Yan.

In EU news
In a similar vein as the European Warbucks program, the North American players will be able to use a special in-game service that is every gamer's wish come true. The World of Warcraft development team today announced the new Pandaren Xpress. With this unique feature, players will be able to order Chinese food in-game using the brand new /panda command. After making a selection from the large and varied menu, a helpful panda will run off and fetch the order. The food will be delivered to most US locations in less than 30 minutes (availability not guaranteed everywhere). Blizzard Europe is working hard to bring this great service to European players very soon. You can find a more detailed announcement here.
