LADIES NIGHT: We like to think every night is ladies' night, but Ai Sushi makes it official with an evening of complimentary massages and manicures. Drink specials include $5 house wines and martinis and $3 sake and Sapporo beer, plus, select items from the lounge menu for $3-$5. All proceeds from dessert sales to the Red Cross for Japan relief, which is all the justification you should need for a sweet ending. 7-10 p.m., 358 W Ontario, RSVP to 312-335-9888.
TWO PIECE PARTY: It doesn't feel like spring outside, but tonight's Bikini USA model casting at Crimson Lounge should help warm things up. Bikini USA is looking for models to feature in its upcoming TV show, calendar and searching for its model of the year.
