We are planning a last-minute trip into the city for dinner Saturday night and many of the places I wanted to go are booked. Looking for a celebratory, hip place for dinner for two, where I can feel I've crossed something off my Chicago dining bucket list. Preferred cuisines include Italian, contemporary, seafood, Gastropub, with good vegetarian options. Preferred areas include Downtown, Gold Coast, River North, River West, and West Loop, although we will have a car. We don't mind waiting a bit for a table as long as there's fun people watching, a good bar, and cuisine that's worth the wait. Any suggestions?
