Let's Do Lunch: Undercity

New achievement added in 4.2, along with Let's Do Lunch: Thunder Bluff. Let's Do Lunch: Orgrimmar is the renamed Orgrimmar achievement, and with the other two award the meta [achievement=5846].

[npc=4552] randomly offers one of the five quests each day, and while you're in town you might as well see [npc=4573] for your daily Undercity fishing quest, to unlock Fish or Cut Bait: Undercity (and subsequently, [achievement=5852]).

Note: Each city's daily quests (Orgrimmar, Thunder Bluff, and Undercity) share availability. As in, you may only do one cooking daily and one fishing daily from any of the three cities, per day. Even accepting a quest from one city causes the other two "!" to disappear.

Appears that if you have completed the cooking quest in one city, you are prevented from doing one in another city. No you can not do all 3 cooking dailies every day. Yeah, I know, bummer for us achievement junkies.

I was able to do the Orgrimmar daily and the Thunderbluff daily on the same day but was unable to get the Silvermoon or Undercity dailies. I was still able to complete the Shatt and Dala ones as well.
