OK, if you're looking for something to eat when you're touring the Country Music Museum, you want it right then. You don't want to have to drive somewhere, or pay an outrageous amount for it.
The Hound Dog is a little food stand right down the street, and at first glance, you think 'how cheesy.' But when you get there, you laugh at the name (they love Elvis in Nashville) but smell the food and love it.
The best thing to get is the lemonade. My mom and I went on 3 special trips back to The Hound Dog to just get the lemonade. It was sweet and sour and refreshing and just what we needed. The hot dogs are pretty good too.
