Here's a nice little article about some revitalization going on in downtown San Antonio. They've at least got the advantage of not having a bunch of torn-up streets making it impossible for anyone to enter these fledgling businesses, unlike some other allegedly downtown-revitalizing cities I could mention. One curious bit:

"The average tourist is in San Antonio four days," [real estate marketing agent Don] Thomas said. "We know they will spend two days on the River Walk. Then they're looking for something else to do. That's when they go to the Quarry, but if they had an alternative downtown, they'd just as soon stay downtown."
