What's the story on the two "world famous" andouille establishments in La Place?

Driving through La Place on Airline, I happen to see two establishments nearly next door to each other that claim to be world famous andouille, one place was called Bailey's and the other was Jacob's. Never heard of either, but also never spent much time in La Place.

Are either of the places legit? Do locals actually eat their products or is there a better place that doesn't rock the "world famous" moniker?

I'd appreciate any info, when I drive back through I was thinking about stopping at one or the other to pick up a few links.
