Just filling in the lots on the east side of downtown, I thought this area bound between 4th, 9th, Jones, & Commerce could be used as a little theater district. Bass Hall and Maddox-Muse Center would anchor that north side, and the lots south of it could be more theaters, dance studios/halls, arthouse theaters, etc. The L-shapped parking space next to Embargo could be converted into a pavilion, and... SOMETHING has to be done with that abandoned Hilton Annex. I figure it could be used as another garage for the area at the very least.
Everything in orange would be "Theatre Row".
