Perhaps "bad real estate" is a strong term, but here's why I ask.
There are some addresses that seem to be a revolving door for new restaurants. It might be easy to assume it's because of the location, although this doesn't completely explain why, if it's in say a strip mall, neighboring eateries seem to do just fine.
I'm curious to know if anyone's opened a restaurant in what was once a "revolving door" and witnessed it becoming a success. If not, was it because the previous restaurants at that address flopped and the new eatery inherited a stigma?
