I'll preface this by saying I've been to Lounge 201 (on Capitol Hill Senate side around the cornor from Red River Grill) for happy hour and didn't really like the place, however we had our company christmas party in the private lounge in the back and it was actually a nice space for hosting small events.
Fully stocked bar with very strong drinks and a good cocktail list, passed finger food (nothing special or overly creative but adequate), lots of couches and chairs for sitting. We had probably a party of 30 people and had plenty of room, I'd say the room could hold 50 comfortabley.
Anyway, if you're looking to host an event on Capitol Hill and need a nice space, then look into Lounge 201
