30th Birthday Party · 80 guests · September 2025
I had a great experience renting out the back part of the bar for my 30th birthday party. It easily accommodated my ~55 guests. The staff was very friendly & helpful. I reserved the room for 3 hours but they let us stay the whole night at no additional charge because no one had booked it after me. Very reasonable price for the size of the place and convenient & cool location! Would def recommend

The space is super great. Holds alot of of people while still feeling intimate. It had room for dancing and sitting, which I think is a hard balance to strike. They were also super communicative and helpful. I truly enjoyed everything about my experience here!
Nothing! Would recommend this place!
