In the morning, I visited Fernsehturm (TV Tower) and walked to Potsdamer Platz via Brandenburger Tor. There, I went up to Panoramapunkt. I came back to the hotel by bus and checked out around at two o'clock. I went to take late lunch at Daitokai (means big city). As usual, I was going to take sushi, sashimi or noodle, and I found Sushi teishoku (regular meal) includes various dishes and the price is reasonable. While I was taking lunch, a family sit at the next table finished eating and left. The guest became only me. I told a waiter that Daitokai is dear because I've visited Dusseldorf for business trip and take dinner at Daitokai so often in 1970's. He said Daitokai in Dusseldorf has already been closed. I changed the topic and I asked him to charge a battery of my camera until I leave, because I took so many photos and still going to take photos, but I don't have any chance to chage at the hotel. He did as I requested. Everythig's went well and I was so much satisfied.
