The 5 stops I use most are (in order of use):

- 53rd Street Metra (bicycle/coffee shop)

- Randolph Street Metra Station (~8 or 9 shops of various kinds)

- Merchandise Mart Brown Line (attached to a mall)

- Clark & Lake CTA in the Loop (entered via 2 different shopping centers or the street)

- Randolph/Wabash CTA in the Loop. No shopping at this one as it is an old, small elevated stop. That said, in the little space it does have available there is vending so it has been commercialized.

The red/blue lines are good examples of what I mean by not having space. Where would you put shops that would generate enough revenue for the work of putting them in to be valuable? The 95th street station used to have a newstand in it but doesn't anymore, I assume because they couldn't find tenants.

There are many shops in the red line. They are only open during the day/rush hour. Some of them used to be good (like a mini c-store or a Dunkin donuts) but often they replace them with something stupid like a popcorn stand, or closed them all together.

Obviously there is also the pedway at Lake St, and merchmart, etc but that's not really what we're talking about.
