In announcing earlier today the new condominium tower he and Astoria partner Roberto Contreras are planning to build downtown, Randall Davis wasn’t so specific about the location he has in mind for the highrise building. But sources tell Swamplot it’s planned for a portion of the block bounded by Polk, Caroline, Austin, and Dallas pictured above. That would put it on what’s now a surface parking lot adjacent to the Dirt Bar (tag line: “We Play Rock n’ Roll”) and across the street from the House of Blues, at the eastern end of GreenStreet (formerly Houston Pavilions). Noodle fans will remember the Dirt Bar spot at 1209 Caroline St. as the former home of Josephine’s Italian Restaurant. The Reserve 101 bar is on the corner at 1201 Caroline St., next door.
