Parking is available at the AC Hotel, on Rush street in between Ontario and Eerie. The ramp doesnt clearly identify it's a TJs parking but when you get to the top of the ramp you'll see the TJs parking section. If you give this TJs a call they'll also give you directions.
Yes parking above the store
To the best of my knowledge there is no parking on Ontario Street in downtown Chicago but I think a lot of people just get dropped off and then friends or loved ones pick them back up at the front door they do allow that I do not know where the main parking is and I'm sure if it is they're going to charge you for it like anything else in the city of Chicago I prefer to go to the Trader Joe's out the suburbs it's a lot more convenient less stressful
i see a note below. thanks
