What is the Chicago building on the Starbucks mug?

Not the old one with the Chicago skyline, but the new one with a single building. I recognize it but I have no idea what building it is. Any help?

1. there is more than one version, but if it the new one with the beige building on it, it is the water tower, located in the gold coast neighborhood, one of the very few buildings to survive the chicago fire
