A visit to Tokyo is not complete without a sushi breakfast and Sushi Dai is one of the best. The draw here is the excellent quality fish brought from Tsukiji market, mere meters away. It's arguably the best sushi breakfast you can get for under ¥4,000 per person. If you know exactly what you want, order a la carte. Otherwise, take the omakase tasting menu option, which opens with a generous slab of decadent fatty tuna.
