We arrived at Daiwa Sushi around 630am. Every sushi place already had a long line in front. A young staff member at Daiwa Sushi told us they temporarily closed the queue in order not to block the alley. He said we could come back to queue at 8am instead of waiting there. We didn't trust his words initially and thought the queue would only get longer if we left then to return at 8am. So we just stood there and kept trying to sneak in queue when he wasn't paying attention. It didn't work! So after making him promise that we could cut the line upon our return, we left to explore the rest of the market for an hour. When we returned, he did remember us and let us cut to the front of the still crazy queue. We then waited for less than 20 mins to be seated. We both did chef's tasting set (7 nigiri plus 1 roll) and ordered 5 additional a la cart pieces afterwards. The total bill came out to about 10,000 yen (~$100) for the two of us. It was worth every penny and the long wait.
