Your favorite casual fine dining picks
I'm looking for "casual fine dining" restaurants: ideal to use for special occasions or as once-in-a-while indulgences, but not absurdly expensive -- let's say no more than 15,000 yen/head max, without drinks. Any particular recommendations? No particular cuisine in mind.
I'm thinking in the vein of L'AS, for example, or Den (I'm a huge fan of Chef Hasegawa's playful, fun and creative take on kaiseki ryori, and I've been making it a point to go back every month!). Anything similar you recommend? Has anyone been to L'Alchimiste?
