I went to Daiwazushi on 5/29/13 at 7:30AM and waited only 25 minutes. The line next door at Sushi Dai wound around building 6 so I didn't even bother with waiting. I ordered the set menu with one hotate as ala carte. The server brought me green tea and a bowl of miso soup after asking what I'd like to drink. The sushi chef served my set in four parts with the hotate following the first part (ootoro, uni, ika, and tamago). The second part was the cut roll of tuna, the third part consisted of ebi and another type of fatty tuna. The last part, which I had forgotten to take a picture of, was the melt-in-your-mouth anago and I can't remember the other type of fish. I guess the anago was too memorable. I finished my set by drinking the miso soup with fish. I think my total bill was around 3800 yen (they only accept cash). After paying at the cash register, you exit through the back of the sushi bar. If you go to the right, you'll end up seeing the long line of people waiting for Sushi Dai. I took the Toei Oedo subway from Shinjuku station and it was around a 20 minute ride. Take the A1 (Tsukiji) exit and you'll see the Tsukiji Fish Market map on your left after getting off the escalator. Turn left after viewing the map and follow the blue outlined pedestrian walkway through the fish market area. You can go to the end of the shops/restaurants and then turn left to look for the numbers on the building. You'll want building 6 for Sushi Dai and Daiwazushi. The first you'll see is Sushi Dai with the really long line of people. Turn left down building 6 to go to Daiwazushi (look for faded, small red curtains).
