The food is the core of Calabash style seafood and has remained fairly consistent for as long as I remember. However, the atmosphere has been modernized a bit.
I grew up in NC and ate Calabash style seafood all over the state in the 50's and 60's. Most all restaurants would serve mounds of fresh, lightly bread, deep fried seafood on paper plates, plastic utensils and at times on long picnic tables covered in brown paper. Florescent lamps or bare light bulbs often lit the dining area. They were filled with noisy, friendly people that mostly knew each other. The food was, hot, plentiful and good. Many times these places would only open on Wednesday night and Sunday afternoon after church. Many times they would be outside of town on a country road with gravel parking lots. All would include "Calabash" in their name.
If you go to Calabash now the restaurants are slick, new, modern buildings. The food is the same, the prices are higher and the atmosphere is no doubt different.
Its still mighty good eatin' though.
