Hush Supper Club
I have been to the Hush Supper Club. Though I like the idea of "secret dining." This particular experience was not worth the money. The cost is $75 and its byob. The food is Indian vegeterian. We started out with fritters which would have been good were they not cold and mealy. Then we had lentils, red peppers, a yogurt sauce, all with a flatbread. She finished the dinner with a kind of puree with a ghee base for dessert and chai. I've had much better chai in many places. What made this experience really intolerable was the long speech the host gave in the middle of dinner on world religions. It was just boring and killed the mood of the whole night. Despite the fact that the food was droll and not worth $75 by any stretch of the imagination, the guests were all getting along wonderfully. However, the host just took the air out of the night by delivering her prepared lecture on the judeo-christian religions and hinduism. I personally don't care about religion at all. The whole reason I, and I assume others, were willing to plop down $75 for this was to get some delicious "knock our socks off" Indian food. My socks stayed on. I could cook better Indian food myself. And I have no experience with it at all.
So my recommendation to my fellow chowhounders is to save your money and spend it at Zaytinya, PS 7, Rasika, or any of the DC restaurants what will knock your socks off for $75.

Go to any restaurant you admire and see if they will cook off menu for you. You can discuss things in advance, invite friends, or interest other Chowhounds. An Indian meal like that should cost about $25 pp. You can eat some fantastic specialized food like that and learn much more about it in the process.
I have had great experiences at local Indian restaurants when engaging the chef for a group to cook "off-menu".
Specifically: Chef Sudhir Seth at Spice Xing/Passage to India, and Chef Vinod at Indique/Indique Heights/Bombay Bistro. Both will not only do special menus, but can do cooking demo/meals if you're willing to go outside of regular meal times.
