So, the girlfriend brought me to Iroha in the valley for by birthday yestderday, and just to contrast the negative opinions I saw on here, I thought I'd post.
I have only been there once, so I can't say if it's gone downhill, but I can say it compares favorably with one of my own sushi faves, Kirala, in Berkeley.
We ordered nothing but sushi:
pampano (which came with special ponzu sauce and a plate of it's flattened and crisped up skin--delicious), I've never had pampano before, but it certainly has its own distinct character,
spanish mackerel (also meant to be eaten with the ponzu, fresh, silvery skin, melted in your mouth), toro from Japan (ranks among the best toro I've had),
spicy tuna (maybe not quite spicy enough, if I have to find something negative),
salmon skin (very nice mixture of salmon skin and little veggies),
and a special Forest Fire roll (frankly, I don't remember what was in it, I know that the top had a huge amount of tuna piled on it, a real delight).
All in all, everything tasted super-fresh and really woke up the old taste buds. Only strange thing was the coupla noodles they put in the miso.
