While there is a Restaurant Depot here in Charlotte, there is also a US Foods Chefstore that has just about everything needed to run a restaurant or food truck.
We buy grenadine for Pammi's Mimi juice there because it's a 32 ounce bottle for the same price Wally World has it for a small bottle.
We've bought a couple kitchen knives and pots and pans there, good quality and inexpensive.
No membership needed either.
