Next time you're West Loop-ish, check out the Chicago Chocolate Cafe at 847 W. Randolph.
You can, of course, buy candies there.
But there's also a lovely selection of sandwiches, soups, salads and super-fancy coffee drinks and desserts.
My suggestion: the half sandwich / cup of soup combo (grilled cheese on peppercorn bread; black bean soup), with a Mexican hot chocolate afterwards. Grab the comfy seats by the fireplace if you can, but go easy on the complimentary chocolate covered espresso beans.
