Chef Sam Diminich is betting big on nostalgia at 3100 The Plaza, where he is turning the former Mattie's Diner car into Grey's Diner and Community Kitchen, with a spring 2026 opening on the books. The plan is to keep that classic booth-and-counter vibe Charlotte regulars remember, while layering in the seasonal, farm-forward sourcing Diminich is known for at his other spots.
Per Axios Charlotte, Diminich, a James Beard-nominated chef, bought the Mattie's Diner site and says Grey's will bring "Michelin-level hospitality" into an easygoing, everyday-diner setting. The team is planning breakfast, lunch and dinner service, with a beverage lineup that runs from early-morning coffee to full evening cocktails.
Grey's Diner already lists an "Opening Spring 2026" timeline and a hiring page. As reported by What Now Charlotte, the project will be run through his Your Farms Your Table group, which centers local farmers and aims to keep healthy food accessible for the surrounding community.
What To Expect
Diminich's Your Farms Your Table group leans hard into seasonal, locally sourced ingredients and community-minded programs, and that mission is clearly shaping Grey's playbook. Expect diner staples reworked through that farm-forward lens, though the team says they will hold back full menu details until closer to opening.
Mattie's itself comes with serious Charlotte lore. The 1940s diner car was hauled down from New Jersey in 2005 and turned into a 24-hour fixture at the Music Factory before closing last summer, then landed in Plaza-Shamrock in 2022, according to reporting by Axios Charlotte. Owner Matt King told Axios he chose Diminich's group because they "respect its history" and have a plan to add value to the neighborhood while he shifts his attention to other ventures. The diner car even made a brief, blink-and-you-missed-it appearance on Facebook Marketplace, Axios noted.
Diminich's other restaurant, Restaurant Constance, earned recognition from the MICHELIN Guide last year, a credential that helps explain the group's focus on both hospitality and sourcing. That track record is fueling expectations that Grey's will marry familiar diner comfort food with carefully chosen, locally driven ingredients.
For now, the fastest way to track opening updates, menu news and job listings is through the Grey's Diner website and the Your Farms Your Table pages, where the new site already lists contact emails and an application form for would-be staff. If all goes according to plan, neighborhood regulars will find their old booths waiting for them, along with a refreshed team, when the diner reopens this spring.
