What defunct retailer do you miss most?

To this day, I still have fond memories of K-Mart. I always got an ICEE, perused the toy aisle, and begged my mom for candy. I also have a spot for Montgomery Ward. There was a good chance of finding something weird there. What long gone stores do you yearn for? Bonus Question: what's in the building where your favorite store used to be? Mine's a cancer clinic!
