I have been a loyal supporter of Wabi-Sabi since the introduction of their miso ramen. My love for them increased tenfold after they made tantanmen and okonomigyoza available. For cold days and evenings, walking to Wabi-Sabi and eating these two things make my day.
They also have a small grocer where you can buy faux meats, salt, dates and vegan fish sauce, etc.
MUST TRY: Tantanmen (if you like it spicy), miso ramen (if you're vegan, ask them to remove the butter), bahn mi, lemongrass tea and okonomigyoza
Cons: No access to clean comfort rooms
