Lakeside Center has a problem - nowhere to put a hotel tower, and it would be hard to retrofit for hotel too. Plus McPier would have to agree to surrender it, which they won't do unless the city pays for the floor area to be replaced further inland.

Tribune Publishing has another slight problem in that there is a church across Halsted, City Church. But they could probably solve this problem with creative site planning, it only rules out buildings near the Halsted/Chicago intersection. TBH it's probably better to put the casino near the south end of the site - right next to the Ohio feeder ramp, closer to the Blue Line, short walk or Uber down Grand to other bar/entertainment areas. They could even ask IDOT for offramps directly into their parking garage.

The 78 is a good site, no red flags. The South Loop doesn't have a huge bar/entertainment scene, but that could be an advantage for keeping people spending money on the premises. And it would be well-suited for luring sports fans on game days (admittedly only a handful of days a year, but more now that the Fire have moved).

Thompson Center actually could be a possibility, looks like it's just outside the 500' radius of Chicago Temple.

Old Post Office is too understated, and historically protected. Nobody would know there's a casino in there.
