Outdoor patio or deck...

I'm throwing a surprise 40th birthday for my husband that is boys only on the 9th. I'd like to do something for us girls while the guys are out celebrating.

It would be nice to have lunch and drinks as part of our day out of doors on a deck or patio. Some place that can seat from five to eight of us. Since I'm still relatively new here the patios that I am aware at this point don't hold a lot of appeal (my sister-in-law recommended Chevy's). I'd like to keep the price somewhere lower than expensive, if possible. Any type of cuisine is fine.

Thanks!
