This is a long overdue review from my experience holding a private event at Broadway Studios last year. The venue itself is beautiful. I organized an awards dinner/benefit concert in March of 2010 here. The stage and sound worked perfect for a full band, our organization's logo and a photo slide show were displayed on their huge drop down screen, tables were organized for the dinner and then quickly moved to make room for the dance party, and working with their sound team was easy.
The catering was delicious and even with over 400 people at our event, it never ran out. It was also affordable. The venue is set up with a big main room and a smaller back room which is where we had food set up (there is also a bar here). The main front room has a huge dance floor with booths surrounding it, a full bar, and a mezzanine that also have booths (great for VIP's or event sponsors).
Francesca is absolutely awesome to work with and her main goal is to make sure that you get to enjoy the event you're organizing - which is hard to do if you don't have a solid team to rely on. They can also set up a photo booth for your party - complete with awesome props and the ability to print photos right their with you company logo on them.
If you're looking to organize a private party, dinner or concert, go check out Broadway Studios.
