Kati rolls are terrible...and for 5 dollars a roll that doesnt fill you up, its not that cheap either.
Mamouns is 2.50, not 2 anymore.
Also you can try Miyabi (near third and macdougal) sushi lunch special. They have lots of different things under ten bucks including 3 rolls for 10.
Banh mi sandwhiches somewhere near little italy and china town for 4 bucks...
