Sushi Sei is an upscale Japanese restaurant a bit outside the city center in Buda. Popular types of raw seafood dominate the menu: sashimi, maki (cut sushi rolls), nigiri (mounds of rice topped with fish filet), and chirashi (fish scattered over vinegared rice in a bowl). Apart from the typical tuna, salmon, and prawn options, Sushi Sei's impressively broad fish selections also include eel, sea bass, octopus, squid, and salmon roe.

The chirashi bowl (€23) is a good way to sample a cross-section of the most interesting cuts of fish. During the summer, cold soba (buckwheat) noodles dipped in a dashi, soy, and mirin-based sauce (€8) are a reviving way to round off the meal. Although mainly a seafood restaurant, non-seafood fans can order excellently-prepared tonkatsu (€8), karaage (€8), and yakitori (€7).

In part due to the sheer size of the large space, which rarely gets more than half full, Sushi Sei's interior can feel a bit uninviting, but the restaurant is a good option if you're looking for an elaborate meal of sushi. Sushi Sei is slightly cheaper than Fuji, a comparably upscale sushi place not far from here.
