These were the spots for Bay-watching during 'Transformers' shoot

Sighting: Bay

It's one of the top celebrity hangouts in Chicago, if not the top, thanks to upstairs club Studio Paris. Of course Bay stopped by.

Jellyfish

1009 N. Rush St.

Sighting: Wahlberg

Jellyfish can probably thank the Bulls' Jimmy Butler for this one. The Jellyfish regular played basketball with Wahlberg at the Berto Center in Deerfield last month and then had dinner with him here right before filming wrapped.

Piccolo Sogno

464 N. Halsted St.

Sighting: Wahlberg, Bay

Wahlberg and Bay had dinner here in August with Mayor Rahm Emanuel. Why? Emanuel's brother Ari Emanuel is Wahlberg's agent. The bigger question is who picked up the check?
