Butcher in New Braunfels?
The only meat market I know of in New Braunfels is Granzin's.It is located on Interstate 35 North as you head toward Austin.You will see there is a big Ford dealership in front of the place which is on 1644 McQueeny Road. For me, I would go the I-35N access road from Schertz and then turn on McQueeny St.
They have a website,www.granzinsmeatmarket.com
Their hours are from 8:30am to 7:00pm,Monday through Friday, and Saturday from 8:30 am to 6pm.
The phone number is 1-830-625-3510.
Under contact us on their site, they show a map with the address.Since you are coming south from Dallas, I'm think you would get off at the Walnut exit.Then go under I-35 and turn to your left on the access road and go up a ways,and you will see McQueeny Road on your right and the big Ford Dealer,and Granzin's right behind them.
