We visited the H Street Country Club a few weekends ago and had a great time. The Country Club is a two story bar that has a preppy argyle theme throughout. Lots of tennis racquetes, golf clubs, weird looking hats. Downstairs they have a couple of pool tables and shuffle board tables. Upstairs they have a nine hole mini-golf course.
Yes, an entire nine holes indoor golf course with full bar service while you play. Better than that, the course is DC themed, so that you have to hit the ball past a lobbyist's briefcase and around zombie Lincoln and through an accident on the beltway.
The final hole is a par three around the Washington Monument. The monument also happens to have King Kong climbing on the side holding a woman.
If you happen to make it to the Country Club try the house lemonade, it's perfect for summer and indoor golf.
