Food is tasty, well-portioned, very authentic.The pretension it is served with seemed unnecessary. Two of us arrived to an empty restaurant, and the waitress refused to sit us in the table we preferred (away from the draft coming from the main door). Then, I requested to have my dish medium, not super-hot. The waitress lectured me on how that was attempting against the integrity of the recipe and "at Nana we don't substitute or change anything". I can understand not making considerable changes to the recipe, but toning back the amount of chilies thrown in doesn't seem like a disrespect tot he authenticity of the dish. Just my thought.
