Whenever I want to get some AYCE sushi, and still keep it fairly "clean" I love going to Goyemon. They have items on the menu that you can enjoy and still be reasonable while dieting, ie. non-fried/greasy sushi rolls. My favorite roll is probably the Ecstasy Roll. If I had to go with a not so healthy roll, I'd go with the Hurricane Roll (shrimp tempura on the inside). On a lucky day, the daily specials may include Toro, Blue Fin Tuna and Salmon Belly.
One of the things that stands out about Goyemon & Sushi Mon, is that their dessert menu is also AYCE. The only other place that did this was Yama Sushi, but no more. For that reason, you can't go wrong with Goyemon. On a busy night, you may find yourself waiting 2 hours. If it's not too busy, the wait may be 15 minutes. Either way, bring your appetite!
