Heading to Tokyo

I am taking a 4-day weekend this week, and Ant and I are heading to Tokyo's Roppongi district to see what we can see. We head down on Saturday morning, bright and early, on the Xinkansen (bullet train for you non-nihongo speaking peeps). I've never been on it in the day time and heard it is a trip. We hope to go to the zoo that day after checking into our hotel. We are also planning to visit the Tokyo Tower on Sunday. One night we plan on visiting the Tokyo Absolute Ice Bar, which is this bar where everything is made of ice, from the tables to the walls, to the art. We'll be back Monday afternoon. I plan to take lots of pictures so I'll post them on here.
