We went back to the hotel (with a short stop at a conbini to stock up on breakfast), and then went out again for dinner. Two doors down from the hotel is a izakaya where we had drinks and dinner. I especially liked the stewed tofu and the baked udon. Now I'm slightly tipsy -- we'll attribute that to the lack of sleep and not to the liter of beer I drank. ;)
Tomorrow we'll do the touristy thing and visit Asakusa, and we'll stop by Akihabara on the way back.
