In a few weeks 18 family members (aunts, uncles, cousins) are coming to park slope Brooklyn to celebrate the wedding anniversary of a great aunt and uncle. We are looking for a place for dinner on a Saturday night, around 6pm that is good, comfortable, quiet, roomy. Walking distance from 6th ave and union. Nothing fancy or hipster. And price point is important. Needs to be low to mid-range. There will be older folks in our party and want to make sure they are comfortable. Convivium osteria looks perfect but it's a bit too pricey. Any suggestions much appreciated.
