Inoko Sushi express in Athens is decent... not as big of a menu of nigiri, shokitini, and tempura as RuSans', but Inoko does have complimentary onion soup (with crunchy fried onions in it). And the deep fried bagel roll I had was pretty good. The eel nigiri was great too. Overall, the food is a little better than RuSan's, but the menu is smaller and they try to package things together into meals so its not as well suited for drunken snacking.
