Becky - you did not say if you wanted dressed up or semi-casual...how about something a bit north and different? The downtown Libertyville area has Vitners winery for some wine tasting then walk a few doors down to Firken or 545 North and end up at Rocky Mountain Chocolate Factory
Here is a link and the atmosphere downtown is charming at night
