Visited the Dapu Lu branch and It lives up to the reviews.
Clean restaurant, easy to access and friendly staff on arrival with a hot towel to freshen up when you sit down.
The restaurant menu is all on a iPad and, as long as you don't manage to flip back to Chinese characters, it's easy to choose a base and then a good variety of meat, veg and tofu to cook at your leisure. Prices are very reasonable, with a meal for 2 plus beer and more food than you can eat for c200 RMB. My only slight watch out is that the spice pot gets pretty mouth numbing by the time that it boils down a bit!
Staff great throughout, will definitely be back!
