Came to Chef Assembly Hall for weekday lunch and decided to get Ramen Isshin. The line up is pretty long but it moved pretty quickly. I ordered the black sesame tan tan noodles which the staff said was most popular and it did not disappoint! It was flavourful and slightly spicy but was not too salty. I have tried other Isshin ramens before at their sister restaurant Kiu, and this one is definitely one of my favourite. Portion wise it's a bit small, but perfect for lunch! I will definitely come back for more!
