The Cabaret gives Indianapolis a small, polished performance room where the emphasis is on singers, storytelling, and close contact between stage and audience. It is a different kind of night out from the city's big sports venues and concert halls, and that intimacy is the point.
Check the calendar before you go, because the value depends entirely on who is performing. When the booking is right, it is one of the better ways to add live culture to an Indianapolis evening without committing to a large theatre production.
