Nice Coin store in Chicago?

Hi, 
I will fly to Chicago this april and i wanted to ask if anyone knows a good and nice coin store in the City?
I prefer an actual coin store and not a bullion or gold store.
Im looking to buy mostly small and old american silver and some standard coins from the 19th century like large cents or 3 cent coins :)
I would be happy for any good suggestions, thanks.

Highly recommend Harlen J. Berk on Clark street.
