Lots of dining, Kamata Station to Haneda Airport
Previous hotel guests said that there was a wide range of restaurants, convenience stores and shops found in the immediate area — which seems to be safe, albeit with some adult entertainment — and some of the dining was said to be rather nice. There is apparently also the option to take a shuttle bus directly to Haneda Airport, although most people seeming found it easier to just walk to the nearby Kamata Station and take a train from there.
