Was yum! We went to Nana recently when it was serving its Khao San Road dinner menu (as they are bunking in together while KSR moves to a new location). Overall the group I was with was very happy! We had the 3 flavour pad thai, panang beef, and massaman tofu. All very good flavour and you could let it was freshly made, and made with care. Prices reasonable and average.
I always debate rating places I really like a 4 or a 5 and 5 is quite steep, but I would definitely come back, I liked the interior colours and service, and I really liked the food! Recommended!
