Parker, SC is a great place to life if you want a beautiful home outside of the growing tech hub that is Greenville, SC. I'm not a big fan of being in the thick of big cities, and even cities like Greenville or Florence can be a bit annoying. Parker is like living in the sprawl of a great area and still having access to all of the work opportunities within Greenville proper.
For the most part, you can get everything you need in Parker itself. Living in Parker, SC gives you access to a wonderful set of great food that goes beyond the standard Mexican, Chinese, Italian, and American cuisine that any decent city will have. There are specific Columbian, Costa Rican, and Mexican restaurants if Latin American food is your choice, while a great set of Chinese and Japanese restaurants are available.
To get more food, you don't have to lament a long drive to another area. Greenville has a lot of different tastes as it continues to grow, and Spartanburg has a much bigger set of established tastes as a bit of Army support jobs enhance the area.
The best areas in Parker, SC are near Furman University for the greenery, and then the center of town with most of the restaurants.
