Chinese restaurants are loud, sometimes cacophonous. This is seen as a good thing. There is even a term for it, which restaurants will use on their advertising. 热闹 (rè nào) literally means 'hot noisy', colloquially meaning lively; bustling with noise and excitement; have a joyful time; a scene of bustle and excitement; thrilling.
"Morning tea' or 'yum cha' is particularly noisy. Retired people get together to drink tea, eat dim sum and have a good shout at each other.
