My favorites:
1 - Whatever Citricos is serving (Sun-dried Tomato and Multigrain are what I've had, but they changed the Sun-dried Tomato to something else now)
2 - Sourdough at Cali Grill
3 - Naan and Papadum at Jiko - this is not free, you have to order it, it's the Trio of Breads and Dips appetizer called Taste of Africa
4 - Pretzel Bread at Le Cellier
5 - Kona Bread with Macadamia Butter
The worst breads I've had:
Sourdough at Narcoossee's
Welcome Bread at 'Ohana dinner
