I have only been to Sushi House Goyemon for all you can eat, but it is fantastic! I am usually skeptical of all you can eat sushi since often times the quality and selection will suffer. This is absolutely not the case at Goyemon.
Their nigiri menu is the typical selections, but they have a huge number of very inventive and tasty rolls. Their version of the 911 roll is the spiciest I have had anywhere since they add habanero pepper as well as the typical chili sauce.
Another pleasant surprise for their all you can eat menu is that there are items available from the grill. I have had the grilled yellowtail and pork belly and both were very tasty.
The service has always been good with multiple servers handling each table which makes it go much quicker with a large group doing AYCE.
I try to show up before 6 since they get busy for dinner, even for weeknights.
