Former Taco Bell Space at 41 W. Congress Becoming Medical Services Office?

A reader writes:

I love your blog and thought you might be interested in this story. I noticed work started recently at the long-vacant building on the corner of Plymouth & Congress (41 W Congress - formerly a Taco Bell / Subway) and found this building permit online: 

INTERIOR BUILD OUT OF LOWER LEVEL AND FIRST FLOOR FOR MEDICAL SERVICES OFFICE WITHIN EXISTING 3-STORY MASONRY BUILDING. BUILD OUT INCLUDES 4 TOILET ROOMS, 4 EXAM ROOMS, 3 ULTRASOUND ROOMS, 4 PROCEDURE ROOMS, BUSINESS OFFICE AND 1 BREAK ROOM PER PLANS.

While it doesn't sound like the sexiest thing in the world, the building has been sitting vacant and I guess something is better than nothing (I know some people will disagree with this mentality, I understand)?

Anyone know anything about this?
