Irving Subs has secured a lease for a new space within the food hall at 1355 Market St. The expansion marks the brand's second location, following its original shop on 12th Avenue.
Why it matters
The owners pursued this second location to capitalize on the improved professionalism and safety observed in the Mid-Market neighborhood. It signifies a strategic move to establish a footprint in the former Twitter headquarters building.
The new 400-square-foot unit will operate within a food hall that currently hosts half a dozen businesses. This site replaces the deli counter formerly located on the ground floor of the building.
The players
Irving Subs
A local sandwich shop that has operated its original location on 12th Avenue for 10 years.
The Market
A food hall located on the ground floor of the former Twitter headquarters at 1355 Market St.
The details
The new site at 1355 Market St. is positioned in the former Twitter headquarters, which rebranded as a food hall in early 2025. Irving Subs intends to utilize the space previously held by the building's supermarket deli counter.
Timeline
The Market rebranded into a food hall in early 2025.
The owner signed the lease for the new location in September 2026.
The shop is scheduled to open by the end of 2026.
Market Landscape
This move mirrors a broader trend of local food businesses integrating into underutilized office building spaces in downtown districts. It pits the independent shop against larger chains typically found in dense corporate hubs.
Shoppers working in or visiting the Mid-Market area will gain access to a new local lunch option by the end of 2026. This expansion provides an alternative to existing food hall vendors within the former Twitter headquarters building.
The takeaway
Expanding into a food hall allows the business to leverage existing foot traffic from office workers in the building. Consumers should monitor the progress of construction at the site as the projected end-of-year opening approaches.
