I am not from Sichuan, so I admit I am not creditable for saying the food here is authentic. But they are for sure delicious, and seems authentic enough for me. I had an amazing dinner here. Corn soup, pancakes with beef, tofu... every dish I tried were well cooked and I couldn't stop eating. Spices are a major part of Sichuan cuisine so most of the dishes are spicy. But there are certainly bunch of choices available for people like me who can't stand the spiciness.
Their menus are full of pictures which makes ordering easier. The restaurant is clean and nicely arranged. Prices are slightly higher than average though.
