Fried chicken joints have the best biscuits. Especially good are Popeyes biscuits.
Biscuits are an art that the southern-based chains don’t need to master, it comes naturally. Popeye’s are great, Bojangles are pretty good if a little salty due to the butter brushed on them before baking. There’s a small regional chain based here called Bicuitville that does an awesome job, as the name tends to imply. But, my favorite breakfast biscuit comes from the barbecue joints, huge “catspaw” biscuits with thick fried pork tenderloin, or decent thick bacon and a lot of it, hot sage sausage, whatever you want. McDonald’s biscuits are bland and dry, I honestly prefer a McMuffin if I’m grabbing breakfast there for some reason.
