There is a new place in Lewisville right on Valley Ridge just west of I-35. Phat Cow BBQ. Its moderate. The best thing on his menu are the ribs and the phatjaps.
Ribs - Go on tuesday or friday evening after 5pm. The guy doesnt like things sitting around so he makes JUST enough. He pulls them on tues and fri after 5pm. So, they are FRESH and right of the cooker. After that (if he has any) they arent quite as good.
The phatjaps are basically jalapeno peppers filled with cheese and brisket wrapped in bacon.
His green beans arent that good however.
Almost every GOOD BBQ stand makes good brisket and ribs. The hardest thing is to find a good place where the sauce is good. Old Town BBQ on 407 and I-35 has great brisket and sausage. Though the sauce is a little to vinegary for my taste.
And to the above.. Dickey's blows goats. Absolutely awful. I hate any place that will weigh the food before they give it to you.
