The ninth floor of Water Tower Place is hosting a networking party Thursday from 6 to 9 PM. There'll be a free, unlimited bar with wine, tequila, and martinis, and edibles such as sushi, beef stew, Thai coconut soup, and cheesecake from restaurant sponsors. Participating businesses will be giving out raffle tickets for a vacation to an undisclosed "special five-star destination." Extra raffle tickets can be had by bringing in toys for the Boys and Girls Foundation. For more information, call 312-643-0610.
