There are three restaurants I distinctly remember long-term as health risks: Chipotle, Chi-Chis (decades ago), and Jimmy Johns.
The first, I still consider a risk. The second is long gone, and exists only as branding for salsa and the like. The latter, made a concerted effort to get rid of the one risky part of their product which couldn’t be cooked or otherwise sterilized (sprouts, by definition) and to my knowledge hasn’t had a large-scale problem since.
JJs is the only one that handled it even remotely correctly, after either the first or second outbreak, by straight removing the risk. They’re also the only one of the two remaining above that I’ll patronize. I’ve never eaten Chipotle, and it strikes me as highly unlikely that I ever will.
