I lived in Waco for a while and have traveled all over the place for work the last 5 years. I eat BBQ wherever I can find it if I hear its good. Mamma and Pappa B's BarBQ is probably some of the best in Waco. You will hear Viteks a lot and that is pretty good too, but this place is better in my humble opinion. Most people that rate this place less than 5 stars do so because of the building (its in a dump). But if you look around and find their food rating, they always give it 5 for the food....and after all, its the food we are interested in right? 5 stars. You won't be disappointed!
I have been going to this place for a while now and to me is the tastier meat I have had in town. All this other places have no taste on the brisket and you always have to add your own condiments. At Mama's and Papa's the meat tastes really good and the sauce is even better. Of course it looks like a run down place, but the best food always comes from the little places. If you are used to eating in upscale places like the previous reviewer your not going to like how the building looks.
Don't drive away because of the looks of building. The food was awesome. They make everything including sauces. All the meats are great. I love ribs so that was my favorite. My husband couldn't quit eating the potatoe salad. Prices are great and service is awesome. Just west of I35. Take the 5th-7th street exit. Stay on frontage Rd until 8th street. Turn right will be a couple of blocks on your left. Real friendly folks.
