I stopped by here because I had around 3hrs to kill before boarding my flight and this seemed to be the only decent looking restaurant right after we got past security and immigration.
I was here mid afternoon and it wasn't very crowded and was able to get a table by the window. We told the staff that we would stay here for a while and to attend us slowly which they did gladly and didn't bother us unless we asked them for something.
We ordered fish tacos and later a mushroom flatbread both of which were good. It can get crowded and noisy, but hey its the airport and that's the best you can get, can't complain about it; just don't plan on attending a business meeting or phone call here.
