Hi, we just returned from 2 weeks on the Sky. Manfredi's, in my opinion is hands down the best specialty restaurant, with attentive friendly waiters. Food consistently fabulous. We tried the Chef's kitchen twice, as you know it is a "fixed menu" and the menu changes every 2-3 nts. I believe, we tried both the Asian menu and the Indian food menu. In both cases, they will definitely push the premium wine pkg. which was cheap at $25, one tasting to accompany each dish. It is indeed a different experience, but I found the waiters to be robotic, they each have their descriptions to accompany each dish. Found the service to be inconsistent and formal, plus tiny portions of food which did not appeal to our table at all. My son and daughter in law accompanied us, they are definite foodies and they were not impressed, as were many of the other passengers we spoke with. If you want a fun birthday, I would definitely do either The Restaurant (which is fabulous) or Manifredi's. We loved our experience on the Viking Sky otherwise.
