I guess this relates to the new Zagat listings that came out this week. Reported first at http://miami.eater.com/2015/1/12/7533....
TODAY (WED): free scoop of Abuela ice cream at Azucar starting at 11am

THURSDAY: Richard Hales will be handing out his notable duck sandwiches in front of Sakaya tomorrow: https://twitter.com/sakayakitchen
FRIDAY: free 1/2 order of medium size stone crab claws at Joe's?! Must be some fine print. Starts at 4pm, but there is a limited number, so not sure if it's worth the risk unless you are nearby.
SATURDAY: free slice of key lime pie at Joe's after 4pm. Again, must be some fine print.
