The breakfast at The Rostrevor Inn is a highlight according to guest reviews with many describing it as delicious, excellent, superb and outstanding. The breakfast is served promptly by friendly staff with some commenting on the large portion sizes. The selection is good with a choice of items including cooked breakfast, vegetarian pasta with pesto and amazing pancakes. Guests also commented on the value for money and quality of the food at the hotel's bistro, where they had breakfast and dinner. While one guest did have a negative experience with the breakfast, overall, the feedback is overwhelmingly positive. The only minor criticism some guests had was that the breakfast should start earlier than 9 am. However, this did not detract from the overall positive experience of staying at The Rostrevor Inn.
