If you are interested in sushi or Japanese food, and I am assuming you are b/c of the recommendations of Social House and Japonais, I'd recommend either Okada in the Wynn or Koi at the Planet Hollywood. I really disliked Social House; it was, when we were there, all scene and no substance, starting with the waitress, who, when we asked her about the Riesling, answered, "well, it's german"...thanks! and later proceeded to try to open a screw top with a corkscrew. Okada has excellent sushi and very good small plates. I have not been to Koi in LV yet, but have been to its LA branch and thought it was very good; more importantly, the new head chef at Koi (which just opened) was formerly the owner of a fabulou and much missed sushi restaurant, Koto.
Stripsteak is one we've been wanting to try, so if you go, I'll certainly be interested in hearing about it. Gourmet mag this month had a very favorable write up on Guy Savoy, and I think that will be our next big splurge.
