Fairegoer's Feast

The Fairegoer's Feast achievement is available during the Darkmoon Faire on Darkmoon Island.

Details
All of the food for this achievement can be bought from the vendor Stamp Thunderhorn. All of the drinks for this achievement can be bought from the vendor Sylannia. Both of these vendors are just to the right of the Tonk Commander daily arena. The drink vendor is right along the main path, while the food vendor is back father behind a few wooden tables.

Tip: By default, these are sold in stacks of five. You can shift left-click on each of these to only buy one of each instead of five to save gold.
