Yeah, two points here:
1. I never claimed such a thing happened. I merely noted that, very shortly after the breach, my birthday was referenced in a promotional email from a restaurant I don't know, and using a site I have not given my DOB to. Something that hasn't happened before. Coincidence? Very possibly - I didn't imply a direct connection.
2. The specific restaurant is irrelevant anyway. As stated, they use a reservations platform that lists dozens of global brands as clients. That could be a more plausible market for the hackers.
