A nice little place, down in the corner of the lower floor, where a person could pick up such essentials as "eye of newt", and maybe some spider webs, deadly nightshade, that sort of thing. And a bookstore with nothing but leather bound editions of the classics. A little chemistry supply store would be helpful as well. Any sort of large, box shaped equipment with as many blinking lights as possible - it could be called "The Large, Box-Shaped Equipment Store" You never know when that stuff might come in handy. Probably some sort of GQ store for warlocks, with all the latest gloves and hats of course. Devilishly low prices! Oh, and for Vicki, the "Sleeveless Only" dress shop. No sleeves - Never!
