I think I forgot to mention this since I am leaving now I am reminded of this - I guess the quickest way to get from Narita airport to downtown Tokyo and back to airport is using the Skyliner express train which takes about 40mins only. Its not the cheapest way though costing 2470 yen or about $30. The train ends up in Ueno Station
This is the counter in Narita Airport to buy the Skyliner ticket
Forgot to post this meal, eel or unagi. Found one of the best known as Nihonbashi Unagi Isesada. Expect to queue.

The food comes in set, a la carte or course. I chosed the most elaborate course. Waiter was worried if I understood because if one look around no one orders course only sets I assure him that I understood.
