One of Misso's servers (who, unfortunately, has since left the restaurant) made a number of clever suggestions to enhance our meal, like steeping our cold sake (a Junmai Ginjo called Shikaiou "Thing") with shredded cucumber, a subtle twist that actually refined the drink. Combining tempura ice cream with deep-fried bananas for a "tempura split" was another playful improvisation.
But it was a recomendation for the uni-unagi nigiri that was a revelation. The creamy ribbon of urchin sandwiched between sweet eel and a pad of firm rice is one of the best "gateway bites" I've found for intermediate sushi eaters who want to be more daring.
