Right now I have four quests identified, there may be a fifth that I haven't seen yet. Here are the screenshots I took of them:
All of these locations are in the vicinity of Stormwind, so the new dailies will require minimal traveling. Also, there are some changes to the denizens of the canals which enable quest completion in and around the city. At least I have found it to be so with the one Cooking quest.
As of today there are no additional Cooking quests available. Unlike the Fishing quest, the Cooking dailies are not rotating. It's the same quest every day, even though the quest giver has a blue ! over him. I assume they haven't yet implemented the other Cooking quests. I'll be sure to post when I see them :)
** UPDATE ** Used one of my pre-made toons to tackle fishing, dropped a primary profession so he could unlock the Fishing ability. I was able to get a functional Fishing button that way, apparently it's just broken on characters who already have the Fishing ability. I went ahead and did the quest even though my test toon had no fishing skill. It took about 10 minutes but he was able to fish up the quest items and turn in the quest. So it appears there's no minimum skill requirement on the SW fishing dailies. And the quests themselves are working, it's just professions that are borked :)
