This is a great recent addition to Mostar, located just outside of Old Town and near the bus station. A great spot for drinks or a meal with both indoor and outdoor seating. Cultura has an awesome selection of traditional Bosnian fare that has the taste of home cooking but also includes pizza (one of the best in town) on its menu.
If you want local food at local prices, you need to step outside of Old Town. Cultura is a fantastic option. The patio space is a lovely spot to relax for a meal or a drink and recently it has become a space for live music in the evenings.
Cultura is located just across from the bus (east) and train station so if you want a solid meal before a long ride, this is a convenient place!
