This is the most authentic Chinese food I have found in Pittsburgh. My husband and I went right after he got back from a work trip in China and he had actually spent some time in Chengdu. The food there is very spicy and very oily and typically multiple dishes are shared at a table and this is what we did. We ordered crispy pickled cucumber, Diced Chicken with Dried Pepper Chongqing Style - a popcorn chicken type of thing with hot chili flakes (fried to perfection! this dish was our favorite) a tea smoked flavor duck -also very good- and a Dan Dan noodle (I avoid noodles but my friends at the table loved this). I have to say this is truly an expansive menu that is not expensive! I really appreciate different variations on styles of food preparations that I enjoy in Chinese restaurants that are open to focusing on different regional cuisines. We have not used the delivery service so I can't comment on that, but the eat-in experience was great. Everyone was very friendly and welcoming, very highly recommended and a unique experience in this area.
