no idea why people go

Maybe there was a time when the duck here was well made, before Da Dong took over the city with his awesome duck this might have been the non-Quanjude duck option, but these days, going here just doesn't make sense. You pay high end prices (close to what it would cost at Da Dong, Duck de Chine, Made in China) to eat in a dingy, grungy, downright dirty restaurant for a duck that really isn't that good. There is a reason why you'll only find expats (or mostly tourists) here, the food isn't that good and Chinese don't like being ripped off.
