Huck Finn's in Pigeon Forge — we've actually eaten here before and decided to show the Mr what it is all about. Basically, if you loved fried food such as fried catfish, fried pickles, french fries, etc... you'll want to stop in for lunch or dinner and enjoy their selections. They have live entertainment at night while you wait for your food to arrive. However, it comes quickly, so the wait time is minimal. They serve all their drinks is mason jars (it doesn't get much Southern than that), and you'll enjoy the Southern hospitality throughout your entire experience.
Alamo Steakhouse in Gatlinburg — this was our first time to eat at this restaurant. (They have another location in Pigeon Forge, also.) We sat outside on their patio and enjoyed the scenery and listening to the water running in a creek beside us. After reading online about their delicious steaks and homemade mozzarella sticks, we knew exactly what we would be ordering before we arrived. For an appetizer, we enjoyed the mozzarella sticks, and then warmed up with some loaded potato soup (their soup of the day). Our meals came with huge salads. We all got filet's with baked potatoes, but dad went for their pork chops and baked sweet potato. No one had a complaint about their meal, except that it was too much food.
Have you enjoyed these places I mentioned above? I'd recommend both of these if you are planning a trip to the mountains. You will not be disappointed.
