Ample-bellied pennypinchers might be used to leaving sushi restaurants still hungry, but now they need not suffer any longer! Sunday nights at Cafe Sushi feature nigiri for a buck per piece. This is no O Ya, but the fish is fresh and the selection plentiful. Tune out the rumblings of the T tunnel beneath you, and hone in on the taste of über rich eel, wrapped in crisp nori and swept with a sticky sweet sauce that smells faintly of BBQ. Appetite not yet sated? Tuna, salmon, tilapia, shrimp, and many other varieties of nigiri are all $1 each, with few exceptions (e.g. sea urchin and yellowtail are $2 per piece). Order away!
