ST. LOUIS – The culinary mind behind a St. Louis favorite is coming to City Foundry next month, and he’s bringing his elevated grilled cheese concept with him. Steve Ewing, of Steve’s Hot Dogs on South Grand, plans to open a brick-and-mortar location in the food hall at City Foundry next month for his concept restaurant, Steve’s Meltdown. What started as a ghost kitchen whipping up elevated grilled cheese sandwiches, soups and fries for meal delivery apps will have a physical location in early March.
