Blue Ox BBQ has left its post at Buzz Mill Coffee last weekend. Replacing the barbecue cart is a new trailer: Ironwood Barbecue, which officially opened yesterday. The menu features the usual go-to smoked meat items, beer can chicken, chopped sandwiches, and sides like roasted green chili mac ‘n cheese and MeMaw’s potato salad. The trailer is helmed by Austinite Leah Sutton. Hours are 5-11 p.m.
