National authority“Feature on the #19 sandwich; states 'For decades, Langer's has been buying pastrami smoked and cured to its specifications by RC Provision in Burbank,' with Norm Langer quoted on the relationship's origin ('My dad found them, or they found him'). Specific, named, reporter-stated supplier relationship -- the sourcing-relevant piece the brief asked to prefer over nostalgia listicles.”

RC Provision
Press“RC Provision's own site (the supplier, not the venue) names Langer's Delicatessen-Restaurant as a customer using its pastrami: 'RC Provision pastrami products are used by the most prominent names in the business, including Langer's Delicatessen-Restaurant.' Supplier-side confirmation of the same relationship reported by Eater above -- a rare corroboration channel (most producers don't publicly name restaurant customers).”
