Available on Jan. 14, the offering features mustard dose infused with 5 mg THC. It will be sold at Ivy Hall Logan Square for adults 21 and over beginning at 12 p.m., while supplies last.

"Chicago has a deep love for its food traditions, and pastrami is one of those classics," says Jonny Boucher, director of marketing. "Partnering with Steingold's allows us to celebrate that heritage while doing what Ivy Hall does best by creating fun, unexpected moments. And what better way to do that than pastrami on rye?"

At the heart of the collaboration is the cannabis-infused mustard, developed with Steingold's culinary team.

"Steingold's is all about honoring tradition while having fun with food," says Steingold’s founder Aaron Steingold. "This collaboration was a chance to play creatively without losing sight of what makes a great sandwich. The infused mustard is bold, balanced and unmistakably Chicago."

The first 100 customers will receive a "High on Rye" Pastrami Kit, including a Steingold's sandwich and Local Style Chip combo voucher, a sample of the infused mustard, and Ivy Hall merch while supplies last.

The "High on Rye" activation builds on the success of Ivy Hall's Pi Day Pizza collaboration with Paulie Gees, reflecting the company's ongoing commitment to celebrating local partnerships and Chicago culture.
