All due respect no they do not and you may have to use an area under the shade tree due to the space inside is limited
Do not know about raw water. But you won't be finding to many places in the area that has places for yoga mats. Get your food to go and find a nice park. Saw your post earlier asking about Dennys. If you are in eastern ky do check Red River gorge . Beautiful sights to be viewed and plenty of room for yoga mats.
Not sure on the water I believe it's raw and there are booths and a bar to sit and eat or grab carry out. There is not a yoga mat area in any waffle house that I've visited.
