You could find this push cart noodle in Hong Kong where you get to customise your bowl with different ingredients.

Much like how you choose your cai fang here, but this is on a bowl of noodle soup.

They have more than 20+ of items for you to choose from, you can select the type of noodle as well.

The beef brisket definitely must get, soft and strong braised taste. I also added Kang Kong, curry fish ball and fried egg.
