Wife and I have been there two times recently for breakfast. Both times about 3/4 full. The food was really good and prices are very fair. Atmosphere is like a country diner and seemed to "fit in" with beach location. The service, however, is very, very slow and not very good. We waited, and waited, and waited, then waited some more to get our orders taken. The waitresses made absolutely no effort to speed up their very slow pace or pay us attention. We about left before ordering on our second visit as several other's around us did. Even those that stayed were visibly bothered and we could overhear their comments. Both times we were there over an hour and a half (for breakfast!). If you want a better breakfast with wonderful service try the Purple Onion in Shallott, NC. Just a few minutes drive from Big Nell's and much better. Big difference and same great prices.
Come on Big Nell, you have a good thing going but improve that service!
