I had two stays at the Prague Hilton around Easter this year and got upgraded to the Executive floor. The lounge IMHO was one Hiltons best in Europe ( better than the Cavalieri or the Paris Hiltons)
The hotel is now completing an extensive refurbishment.

I have to disagree with you regarding the food ( but then there is not much I dont enjoy in the food department )
Czech food like most Eastern European cusines tend to hearty and meat and game based which IMHO cant be all bad

The Hilton has just opened a very nice restaurant called the Chop House and I had the Pig Knuckle entree there, which was the size of a small ham and one the most delicious roasted pork dish I have ever eaten. ^
