Shower location help

Okay, ladies, my mom needs some help on locations.

We are looking for a place in either Nassau or Western Suffolk that can accomodate 30-50 people. We would prefer a 'loungy' type of vibe, meaning a place that has couches, or a teahouse/coffee place/cafe type of place.

Milk & Sugar is already booked:(

TIA!!

Broadway Beanery in Lynbrook (516) 596-0028. I know they do catering, but I'm not sure if maybe they close the restaurant sometimes to have parties. The place has amazing food, coffee, service, etc. HTH!!
