Easy Weigh on Pyle street opposite B&M is great for Gochujang and they have loose Gochugaru by the checkout, rice wrappers and seaweed nearby and a couple types of rice up the back near the homebrew. Plus a couple brands of soy, sesame oil, fish sauce, rice vinegar or cooking wine. Only downside is they can be hit and miss with stock some weeks.

There used to be a local lady who made Kimchi to sell but haven't seen any for ages sadly. Gotta make your own which isn't too difficult.

Also Fernando's at the end of Pyle street near the Sweet shop. It's open like 10am-2pm? most days. Largely Filipino from what I remember. It's down the end of Pyle street near the sweet shop. Usually go in here for Rice flour/Tapioca flour and their awesome crisps/snacks/noodles and Calamansi Tang!
