The Valdrakken Inn contains a secret room with a private bartender who sells drinks!

When you enter the Valdrakken Inn, go to the statue located at the back and perform the /kneel emote.

This will teleport you to a secret room with a private bartender.

There’s a barkeeper named Kritha who sells Enchanted Argali Tenderloin, Azure Leywine, Critter Kebab, and Emerald Dreamtime. You can also set your Hearthstone here.
