We ate at Trifelli just the once, but would be happy to recommend it.
Run by a German lady and her Greek husband, the service and food was excellent and good value.
The house white wine was the easily the least expensive in Lordas. ( less than 5 Euros for 1 litre)
The restaurant is tucked away and quite low key ( no sea views)
We were the only Brits there! - it would appear to attract a lot of German customers.
