Noticed they have staked the empty lot to the west of Del Taco on 19th Street....any idea on what it will be?

Strip center.

What's really interesting is if you flip through the renderings this location map included shows a Cinemark next to the AtHome but I can't seem to find any info on that and I can't imagine them trying to build that close to the Warren.

No Cinemark. The 'At Home" was built in the spot where "Cinemark" is listed as being located. The area behind the Cinemark and The 24 Hour Fitness(which is now "Golds Gym) has been zoned for residential/commercial. The city hopes to build apartments above and stores below and make it a mix of shopping and residential.
