It's great: walk in, get a bowl, smush as much into a bowl as you can, add sauce, they cook, you eat.
Pick the meats you like. I usually stick with beef. Add veggies. I pick lots of mushrooms. I add tofu to add protein. Pour on sauces to flavor. They have recipes posted to guide you. Then hand your bowl over to the chef and he cooks it and gives you it back all nice and hot in a clean bowl. You can then add a bowl of rice, get a bowl of soup, a glass of something to drink and you're all set.
I used to eat here a lot when I lived in Mesa. We were up here so stopped in and enjoyed lunch. It's a great value for your buck!
