i guess my opinion on the club was more of an absolute rather than relative comparison to other clubs. as a disclaimer i've never been a huge fan of eating at the clubs since i'd always rather go out and eat at real local spots, but that's not saying i've never enjoyed the food there when i've taken advantage of it. i did think their breakfast spread was good, maybe using decent might've had a more negative connotation. i've also enjoyed the breakfast spreads at the GH tokyo.
I felt the GH HK evening spread was just so-so when I was there though since most of the selection was for salads, and cheese and crackers, but not much else in terms of hot food. If i remember correctly I thought the evening spread at the hyatt on the bund shanghai was pretty good as they had a wide selection of foods when i was there last year.
