Our family is extremely excited about this since we live just 2 blocks away! They just posted this on their Facebook page tonight.
With this in mind we went on a little walk and snapped a picture of Mariano's in its current stage:
Upon sneaking a peak inside, it looks pretty good. It's ready for the shelves and looks like October 8th is definitely feasible.
For those who want more information here is a link to some older posts we've done (here, here and here). If you remember the impending construction of Mariano's was the #1 story (in terms of pageviews) on Sloopin in 2012.
