Yes, you can pay a lot more for sushi at Michelin multi-starred counters if you want to, but Kyubei offers excellent quality-fish at somewhat more affordable prices, especially at lunchtime, in a much more relaxed setting. (Some of the chefs even speak a bit of English.)

Kyubei were the inventors of gunkan-maki (the wrap-around technique for fish roe and similar sushi). Lunches start at around Y8,200 for a nigiri set menu, or Y22,000 for kaiseki. Dinners start at Y11,000, with a Y33,000 kaiseki sushi menu that's quite a spectacle.
