I have been to a relatively new sushi bar on Avenue A between 14th and 13th street about four or five times in the past three months. It's called Sushi King and IMHO is a fantastic deal as well as having pretty damn good fish (Sushi Yasuda, its not).
When I hear of any sushi place thats offers some special pricing I'm immediately turned off because I'd rather eat some really fresh, excellent quality fish with a great selection at full price than have lots of cheap blah (or worse) fish. Well, this place is one where they have sushi on little boats floating by each patron and can be had by just removing the plate from the boat, each plate, regardless of the contents, is $2.89. I have had great fun and excellent fish at a restaurant in Japantown in San Francisco that has a similar setup so I just had to try this one.
I must report that I was really surprised. The bar around the little boats is quite large and comfortable, the fish is extremely good, the quality and variety is wonderful and the wait-staff couldn't be nicer. Even the desserts are good, especially the lichee ice cream and it is often complimentary.
I have had, among other things, salmon, hamachi, eel,ama ebi, uni, taco, ika, spicey crab,and many kinds of maki and they will make you anything else you might want (all at $2.89 for 2 pieces.) I have eaten LOTS of sushi in Japanese restaurants and I've been to the top places on both the east and west coasts and, of course, this stuff is not in the big leagues but for the middle leagues, I think its sensational.
