There’s an interesting new business listing on Yelp for what appears to be a weekend-only, all-day pop-up serving Persian food at 50 Fremont St. (I’m guessing it’s outside, in the interior plaza there.)
Horest, which apparently also does catering, has an evocative website:
Horest’s Facebook page mentions mentions “Salesforce Tower Plaza” as a location; that’s probably the same as the 50 Fremont Plaza.
