Antarctica is a continent; the Antarctic is a region on earth.
You can review the list of research stations here:

After further research, I have confirmed that there is in fact KFC in Antarctica.
None, there is only scientific research stations in the antarctic.
Each country supports its own research station on Antarctica. All of Antarctica is "controlled" by the Antarctic Treaty.
If you include the islands surrounding Antarctica, there are 70 seasonal and year-round research stations.
No, but there are research stations funded by governments that signed the Antarctic Treaty.
Research on the Antarctic continent takes place in the research stations or in field camps, depending on the science involved.
There is no commercial whaling in Antarctica: some countries hunt whales in Antarctica under the terms of The Antarctic Treaty, and purport that the animals are for scientific research.
Antarctica is a continent; the Antarctic is the region on earth where Antarctica is located. So in traveling to Antarctica, you are automatically in the the Antarctic.
Research conducted in Antarctica is shared with all the countries that are signatory to The Antarctic Treaty. For example, the best aerial maps are courtesy of the USA's CIA.
There are no cities on the continent of Antarctica. There are research stations, and there are times when the largest station is McMurdo Station with a transient population of about 1,000 souls.
The research isn't temporary: the scientists and workers who support science only work in Antarctic temporarily.
People who work and live in Antarctica are fed by the governments who hire them. There are no commercial restaurants per se on the Antarctic continent.
