My guess would be that you are talking about Lakeway Smokehouse
WYLIE: Lakeway Smokehouse
3995 Parker Rd.
Wylie, TX 75098
Open Sun-M 11-8, Tues-Sat 11-9
If you come from Plano on Parker until it ends then turn right go to the light and turn left it's there. They also do bbq prime rib on Fridays.
Where is it exactly? Drove down that way yesterday for Big Daddy's Roadhouse which btw smokes a good rib and hot link. The brisket/sausage was ok when I had it, the sides there lack a little seasoning. Didn't happen to see the trailer as I passed through Wylie though.
