I am sorry to report that Radisson has recently ended unlimited free caviar. New policy is free in cabins when served in restaurant. Otherwise $25 per ounce. Same for special order in restaurants days it is not served. Don't know how much push back from pax so don't know if policy change will be rescinded.
I never partook of caviar in cabin, just when served at dinner, parties, and lounges so it is not a big hit; just don't like going backwards.
