Everything was perfect! I heard "the best meal I have EVER had" from several guests. It was so delicious and perfectly prepared. The Chef delighted us with his description of each course. Every one of the staff treated us like royalty! Our DC Chapter was founded at the Mansion on O and we all feel as though it is our home in the nation's capitol. Many thanks to H and Ted and all of those who have welcomed us time and again to the marvelous, magical Mansion on O!

Completed a self-guided tour (Espionage Hunt) here with my wife. The team here is great, and super friendly. We had a great time looking through all of the rooms and were increasingly excited with each hidden door found! I would recommend checking this place out

If you are trying to fit in everything when you come to DC, you can fit literally everything in one trip to the O Museum. Shopping? Just about everything you find in the decked out rooms is for sale. Games? They have a pool table, pinball tables, and more.... you just have to find them. Get a drink or snack? They have great cocktails. History? Yep! See Rosa Parks' room as well as a room dedicated to John Lennon. This is just a few of the 80 rooms you can see. We were hoping to blitz through them, but it was more fun to stop and look around carefully at all of the interesting things. There was even Judaica! The staff was warm, personable, funny, and helpful. This would be a fantastic experience for kids. There is also an elevator, making most everything handicap accessible. The direction video is also signed and available in multiple directions. They thought of everything! I couldn't recommend this highly enough. I couldn't believe they also have rooms available for reservation. Someday, I hope to do this.

The Champagne and sweets were fantastic, really made the event special. We loved all the rooms, so much to see and interesting things to look at.
