It is not Indonesian but Malaysian and I have not been for a while, but if memory serves, you can find some Indonesian dishes at the always-popular Penang, on the corner of Wentworth and Cermak. If you do a search on this board, you should be able to find several mentions of Penang and, I imagine, varying opinions of the food.
Good luck!
