i can only write about their location in guijie, which i take is the original place anyway
for many years i have always taken my foreign guests and clients there to eat chinese food which can easily be enjoyed by western standards, and indeed i still go there sometimes in summer because the courtyard atmosphere here in the rear parts is still really unique and really hits it off from a western perspective... and the food, well, is quite delicious for the western tongue, too, which still makes it worthwhile as a show of old beijing for guest from afar...
but
i am definitely not going there anymore without guests from abroad: the prices have been waaaay over the top recently (especially the beer is totally overpriced), while the quantity served in the dishes did not keep track with that price raise, the waiting time increases at the normal dining hours, and the atmosphere in the big front courtyard is getting more and more carnevalesque with rather stereotypical performances...
the place has just been too popular and successful to keep up the quality that they used to maintain before... and thus it goes the way that many other places in beijing go: the value for money ratio is just not worth it anymore...
