Yesterday, after walking around Harajuku - Aoyama area, we went to Akihabara the electric town. After that our friends took us to a Yakiniku (korean barbecue) restaurant. We had to wait for an hour but it was delicious. But I will recomend to book a table is you want to eat @ Tokyo-en!

The old public toilet (no separation between man & woman) is in the back lane instead of in a restaurant. If you can wait for another 10mins, a clean toilet is in the Ueno station.
