It's a shame that so many good choices are closed Sundays, especially Kiki's Bistro. Le Petit Paris is probably not a bad choice, but having lived in Streeterville forever, and having tried to find good bistro food on Sunday night many times, I have never had a disaster at Gabi. It's always festive, always jammed on Sunday night with people enjoying themselves immensely. Steak Frites, Profiteroles, the usual suspects, are always good, service on a bad night is always satisfactory. Once, a lady in my small party didn't like her entree. The waiter apologized, returned immediately with a menu, quickly brought a new entree she chose, and we were not charged for either one. They try.
It's not perfect, but it's right on Lake Shore for an easy trip down to I-55 and out to Midway, valet parking is offered, and I bet the Father's Day crowd will be even more ebullient than usual, if you can get a table.
