I had occasion to go to Austin a few times this past year, and the first time I stopped at a huge meat market/bbq place in Elgin, won't do that again, worst bbq I ever had!
Second trip I spotted this little red bldg up a horrible driveway, and I turned in!
I was pleasantly surprised when I went in, it was very clean, also very homey!
The place is run by two brothers, and the bbq will melt in your mouth!
It's called Dusty's Barbeque, on hwy 290 East - Manor, Texas 512-272-8059.
Coming out of Austin, it will be on the right hand side of the road.
