Not AYCE but I just tried OSAKA at 8855 Greenbelt Road in Greenbelt MD.
They have a happy hour special where you can get a limited choice of
nigiri at about 50% off.

I tried hamachi $1.35 a piece vs 2 for $4.50 regular, eel at $1.25 a
piece vs regular 2 for $4.75, and salmon at $1.30 a piece vs regular 2
for $4.25.

Compare to the AYCE place the rice is about half the size and the fish
pieces are 2 to 4 times larger. Tastewise I was not impressed. Seemed
tasteless to me.

Several years ago there was a place Ben-Kay is Washington, DC. Their
hamachi nigiri tasted wonderful whereas their hamachi sashimi was
tasteless to me. I guess they made hamachi nigiri to my liking.
Haven't had any I really like any where else. Too bad they folded.

Although you get your money's worth in fish at Osaka, it did not tickle
my tastebuds. I like a second opinion if available.
