This week as friends think back on the life of R.C. Webb, many are calling up memories of the Nic Nac Grill.Webb, who died Saturday evening at age 90, is survived by his wife, Ella Ree Webb. He outlived by more than two decades the restaurant they owned and operated for 46 years, from 1946 through most of 1992. But Webb’s Nic Nac Grill and Restaurant on East Main Street was once Statesboro’s largest restaurant and became an instrument of Webb’s quiet, lasting influence.“Mr. Webb was a very quiet person, but he supported high school sports, he supported his family, he supported the local recreation department,” Frank Hook said.
