Had the opportunity to try Percy Street last week. Had a great time.
My wife and I both had the "double down" which includes two types of meat and two sides each. I've read complaints about the price, but four separate meats and four separate sides @ $17 each at a restaurant is too expensive? You'd have to eat exclusively at Chinatown to think that's a lot of money. And we had to take home a good bit of the food at the end of the night.
As a sausage maker myself, I thought the smoky sausages were great--juicy and flavorful. I've heard rumblings of a cheese and jalapeno variety on the horizon, which happens to be one of the favorites of my Austinite pals. The brisket was juicy, the burnt ends rocked, and the ribs were succulent.
Honestly, I'm no expert in bbq. I smoke my own pork shoulders, ribs, & sausages, but I have no first hand experience with real TX 'cue. But I could tell that great care went into all the meats. And frankly, the only thing I really care about is this--was it delicious? We certainly thought it was. The sides were all pretty solid, but the real standout was the root-beer chili. Good stuff.
I wasn't terribly thrilled with the Manhattan I had as seemed shaken instead of stirred, but that's a personal thing. And our waiter hung on our every word until he became harder and harder to track down. I think at one point he said he'd find out the "seasonal brew" and never did. He seemed overwhelmed, which considering the timing of our dinner (early Friday evening into the full-on dinner rush) wasn't completely surprising. Still, it was a serious misstep that we couldn't find him for so long.
If I had any suggestions about dining at Percy, it's that you leave your preconceptions at home and dig into as many of the meats and sides as you can. We were stuffed to the point where we had to retreat to Chicks for some serious digestifs. Phoebe did a great job as always custom crafting our drinks, but that's another story.
