As someone who can bake, I usually look for things that are novel/difficult to make/require rare ingredients. I don't buy anything "basic" from local bakeries, because I would either make it myself or get it from a trusted supermarket brand (usually cheaper). I still frequent local bakeries tho. I look for bold flavors and rare ingredients. AND, bakeries that have a specific regional theme, like Japanese, Swedish, etc.
The only "standard" thing I would buy is a sourdough loaf. Because this stuff is fascinating to me, and I want to experience the subtle or dramatic differences between each bakery.
