I went to Nana during peak dinner time on a weekday and was so glad to get a table as Khao San Road almost always has a wait.
The food was as expected, very delicious! We started with the fried chicken which was so good I was tempted to get a second order. I then got the pad thai which was perfect. The staff were wonderful, very kind, and attentive.
The only reason this is a 4 star instead of 5 was the quality of a few thing. The cutlery might as well have been plastic, I'm not sure what it was made out of. The plates were all plastic, along with the chairs. I'm, by no means, heavier than the average person, but I felt that a leg could have easily broken off. I understand the whole "street" style but I do expect something a bit better when dining out. I also feel as though the hot sauces could have been presented in something other than large water glasses, it just felt cheap that they couldn't find something appropriate to use.
