What time of day was this? 2 years ago I was in the Business lounge (which the dining areas meet up, and have the exact same thing), and they put out only for a short time some dumplings, they were fresh, but gone quickly.
I would agree they need to at least refresh it more often, but the dumplings they put out weren't bad.
the others I saw just eating.....cup o soup, yea bit odd to eat ramen noodles at the lounge.
I am coming from a US centric perspective, their food offerings were better than most in the us
I have a 7 hour layover on my way in so I am sure I will get my fill of current offerings to give a very good spill on what could be done.
