Check out A Fine Swine BBQ. Not in St. Louis, but David has three or four locations. One may be close. He is a friend from BBQ competitions and from what I have heard from other friends he does an amazing job!
Salt and smoke was a huge let down. Ordered the rib and brisket platter. Both dry af. And they cook Texas style brisket, and don’t cook true grilled STL ribs!!!
