The Rumpus Room at South Lake Union
Rumpus Room:
The Rumpus Room is a loft-setting on the upper floor of our Lunchbox location in Southlake Union. When you enter this space, you will feel like you’ve been warped into the 80’s!
This room is very open and one of a kind! The space works great for any kind of social gathering. From birthday parties to rehearsal dinners, company networking events to holiday parties. We can accommodate sit-down dinners, or casual mixers.
If you are looking to hold a sit down dinner, the maximum capacity in the Rumpus Room is 55. If looking for a more casual, cocktail-style atmosphere, the space can hold up to 85.
The room can be decorated however you like, we have no restrictions on outside decorations. Although, you surely won’t need much as the space is decked out to the max! Guests also have control over their music. You can choose from our Comcast stations, or bring in your own iPod. The surround sound speakers play throughout the whole Rumpus Room. If looking for more entertainment, feel free to bring in a game console. A lot of fun can be had with a Mario Kart or Wii Bowling Tournament!
You can rent out more than just the Rumpus Room. Why not reserve the whole restaurant as well?
