first of all, Cordis has amazing location in the heart of Mongkok, close to the MTR and to the Langnam mall with tons of eating options.
The staff was so nice and helpful, for example they helped us pack food from the dining room brrakfast for our airport journey.
The room was great in 38 floor with amazing views of all the skyscrapers.
The breakfast was hands down the best I had traveling abroad. Such a wide variety of foods, new tastes, this was fantastic.
If you're staying in Hong Kong (we were 2 adults and 3 kids), that's the place for you
