Which Texas BBQ joint has the best iced tea?

If you know me, you know I'm a huge iced tea fan. Most restaurants, including BBQ joints, don't have strong iced tea, in my opinion. The rule, sadly, as opposed to the exception, is that a restaurant has weak iced tea. It's just a waste of money. Might as well opt for a free water. But every now and then, I find a BBQ joint that has strong, dark iced tea. Of all the Texas BBQ joints you've been to, which one has the best iced tea?
