Our event could not have been better. The afternoon was perfect. We were all blown away! Iso and chef were outstanding. The staff were so attentive and informative. Our group of nurses and doctors will be back. Thank you for a very memorable evening.

We visited the O Museum to explore the rooms and discover the hidden doors. We spent half the day searching for hidden doors, retracing our steps, and shopping for interesting items. We found 24 doors and were done for the day! We will return to search again. This is an amazing place to explore, enjoy, and relish what the O Museum has to offer those who enter. This is a hidden gem of Washington DC. You can uncover the hidden doors if you are willing to search and keep an open mind!

I cannot recommend this experience enough!! We took my little sister there for her Bachelorette and it was such a fun and unique experience! So much to look at and room to explore! Reuben was hilarious and kind which helped make the experience even more fun! Definitely make time for this!
