The prevalence of those restaurants does not equal a high demand. People who choose to go out to eat don't choose who own those restaurants, they just want to go downtown.

Do you ever wonder why there are so many great authentic Mexican and South American restaurants on North Broadway, but you still will get a papis tacos near the waterfront? There just isn't much diversity in food,generally,in the tourist areas, and atlas doesn't help that.

Go to New Orleans and tell me there isn't a big difference in what is offered, not just in food, but in entertainment. That's just an example,phili and DC are also more diverse,if you want better local examples.
