What are some interesting side-quests or items in BG EE in the actual Baldur's Gate town? I'm about to enter the town for the first time (again) and I want to experience something new. Unfortunately I have always run out of steam doing all the optional quests before talking to everyone, and just give up and start progressing along the main quest to Candlekeep.

I know about the golden pantaloons stealer (and Mr. Shade).

What obscure interaction/side quest should I look out for?
