Outdoor Engagement Party Spot??
I'm not sure how many people you are planning for but Enoteca Roma has a beautiful backyard garden. If you have 6 or more guests they will put together a full tasting menu for $25 a person. I did this once for a friend's birthday and they brought out a charcuterie tray, bruschette, salads, pizze and paste. They brought as much as we wanted and it was really a fun way to celebrate.
Here's a link to their website: http://www.enotecaroma.com/
