if you like spicy, the waiter will give you a dish of spicy pepper oil when you ask for it. Most hong kong people will add red vinegar and spicy pepper oil when having wanton/ / fishball / beef offal noodles, i think Marco will love it! Sour and spicy beef noodles can be tried in tamjai samgor, you can pick whatever you like in the menu, english manu can be search on the internet, try it when come to hong kong next time☺️
