This is such a cool venue. From the exposed brick to the industrial ceilings and all the low chandeliers, it was probably the most complimented aspect of our wedding. The staff did... an amazing job and everything ran so smoothly.
We had invited 300ish guests and had about 220-230 RSVP yes and probably about 200 showed up. I would say this should be your maximum if you're having a wedding here. It was a little cramped with 9 at a table, but we wanted to have space for the dance floor, buffet, gift table, etc.
I'd say our only downside was running out of food/not having seconds for anyone. Also, the venue is attached to a bar so we had some wedding crashers, but that comes with the territory I suppose!
