Micro-Mini Wedding Venue?

Hi! We're looking to get married in about 18-24 months and looking for something for between 50 people or so. Budget will be about $7K. I know tiny, but we're poor. :'(

Ideally between Boca and Martin County

It doesnt need to be a dedicated wedding venue, as looking outside the box, but it be nice to be a restaurant with a private room so we can not distract others. Maggianos is currently at the top of my list, but need some other ideas.

Also in need of a place for a ceremony thats not outdoors. No beaches, no parks. I dont want to be in the heat, rain, or have my allergies & asthma ruin the day. We're not religious, so churches and the like are off our list.

Thanks for reading and thanks for any ideas suggested.
