The Golden Deer Pub is a local pub at Verda Plaza in Etria. Townsfolk and explorers come here to relax and talk after a hard day's work.
The pub is where guilds can accept requests from the townspeople as quests through Valerie, the publican. Quests are unlocked as you progress through the game. For a list of quests, see Quests (Etrian Odyssey I).
