Travel to the Grim Guzzler inside Blackrock Depths with the Direbrew’s Remote.
You get this from the Keg-Shaped Treasure Chest on the first run of the day of the Coren Direbrew dungeon during the Brewfest Event.
Learn more about the Coren Direbrew Dungeon here.
When you use the Direbrew’s Remote it will summon a drill house that you can enter that will transport you to the Grim Guzzler.

The Grim Guzzler is a bar which features many NPC’s.
Some of these include:
Plugger Spazzring - He sells a few interesting items, including rare recipes
Lokhtos Darkbargainer – He is from the Thorium Brotherhood. Visit him to turn-in quests to increase reputation, as well as buy special high-level patterns earned from that reputation.
