Excellent nightclub. It was like a bit of Las Vegas right in the Chicagoland suburbs. We saw a great blues-rock band called Brookwood Drive there last night. Not too big, not too small... tall ceilings, so you don't feel crowded. They have excellent food, a good selection of spirits (including some outstanding single malts), a good craft beer selection, plus wine & mixed drink lists. The front half has tables for formal dining (china, stemware, candles), wheras the back half has sofas & groups of comfy chairs around coffee tables. The bar spans the entire back of the room. The friendly staff are attentive. Everything about this place is classy.
Other reviews talk about standing room cincerts, so maybe they configure the room differently for different events, but the layout I describe above is how it was for Brookwood Drive.
I see from their website that they host conventions, wedding receptions, have many bands scheduled, & an upcoming New Years Eve Celebration.
The complex also contains a yoga studio, performing arts center, but I didn't visit those, so can't comment on them.
I highly recommend The Matrix Club.
