Default NearestDinners Routine

I have worked my way to the FindByLocation routine (page 141) and it will not work. I have verified that everything is correct prior to that but I get an IDE error telling me that NearestDinners does not exist in the current context. I have tried searching the web, placing containers in front of the call, and many other things. What is the fix for this?

Default NearestDinner Function

Totally missed from the book and code snippets - but here it is from the sample site:

Code:
//
// Helper Methods

[EdmFunction("NerdDinnerModel.Store", "DistanceBetween")]
public static double DistanceBetween(double lat1, double long1, double lat2, double long2) {
	throw new NotImplementedException("Only call through LINQ expression");
}

public IQueryable<Dinner> NearestDinners(double latitude, double longitude) {
	return from d in entities.Dinners
			where DistanceBetween(latitude, longitude, d.Latitude, d.Longitude) < 100
			select d;
}
