I really liked the lounge at the Hilton @ AMS airport. While it was small and nothing to rave about in terms of evening food or breakfeast (but we got coupons for the full buffet for free without asking), it features very nice views of the airport and one runway mainly used for arrivals...and a decent selection of drinks that were available on self-service basis as much as you liked (I think the four in our party emptied two bottles of wine while watching airplanes coming in).
