I got this email which states this deal is good at all Southern California
locations: Link: http://ra.chipotle.com/email/11-lax-084.htm
But this thread was posted for Northern CA: http:// 9044
So I'm guessing that while the emails may be location-specific the deal
might be more widespead. If you need 5+ burritos call your Chipotle and ask
if this deal is good there.
