My friends and I rented out the roof and speakeasy of Oasis for a night time wine tasting and it was absolutely perfect for a group of ~35. The space is clean and well-appointed, with ample seating, tables, and lighting to set the right mood, and the owners/manager, specifically DJ, went out of their way to make sure the space was set up prior to our arrival. Their communication was also top-notch. They even left a small gift for my birthday, which was such a kind touch!
We also found the location to be ideal given that the surrounding buildings are - for the most part - office space, which meant we didn't need to be super concerned with bothering neighbors with noise at night.
I highly recommend renting the space for personal events, and the rest of the floors are equally as nice if you need a corporate space.
