As promised in the "openings and closings" thread, they're now open in the loop.

.
The cones have received high praise in the Taste of Chicago thread, and I'll confirm that they're very good indeed. $2.79 for a small (pictured) which by loop standards is practically giving them away. For those not familiar, the rainbow is chocolate, strawberry, Palmer House (walnut & cherry), pistachio, and orange sherbet.
Sharing a space with the Halsted Street Deli, which looks worth a try (I gather there are several loop locations).
