1.) Franklin Barbecue. It'll change your life. Best brisket on the planet. Amazing ribs.
2.) LA BBQ. Started by a former apprentice at Franklin.
3.) John Mueller Meat Company. The son of the legendary Louis Mueller who has been doing BBQ in central Texas for decades. His beef rib is something serious.
4.) Micklethwait Craft Meats. Very, very good. This is a place to get a variety of things -- go with a group and order a pound of everything.
5.) Stiles Switch. My go-to, simply because it's easy to get to, air conditioned, and they don't run out. It's number 5 for a reason -- the top 4 are better -- but this is the place you go if you don't have the luxury of planning around a trip to get BBQ. Good brisket and an absolutely phenomenal beef rib.
You can't go wrong with any of those 5. Now, on the other end, regardless of what you hear, steer clear of Salt Lick. Place is unbelievably overrated.
Enjoy!
