We have been twice during the last week. Excellent service, reasonable prices. Typical Bulgarian, very much like the Bulgarian Village restaurant in the Murgavets. There is another new restaurant just a little further on than the White Hart called Chanove. This is worth a try too if you like the bulgarian theme.
Last year we had a lovely meal in the restaurant opposite the malina village( we were staying there). Nice food, nice friendly staff and a traditional feel to the place.
