Where to pick up those infinity miscellaneous quests in Solitude (where you have to kill Giant or Bandit leader)?Looks like The Winking Skeever inn keeper has no radiant quest option,he has only rumors .

The housecarl at the Blue palace gives you some & the court wizard. At the Inn. The arms trainer. Vagabond on the street. The Bard's college.

Talk to falk. He'll set you up.
