I think the most important thing about mutton kebabs and baked sweet potatoes is the original flavor. Personally, I think the gas stove is better, and it is also suitable for mobile and portable. You can go to the mall or search online. A friend of mine is also in the barbecue business. He bought it from Wang Sheng. They specialize in selling commercial appliances. You can go up and find out. If you don't understand anything, you can ask their customer service. I hope I can help you.
