Armenian cuisine is an intricate blend of flavors and techniques influenced by the geography and history. It offers a variety of dishes which focus on the quality and freshness of the ingredients. Yerevan, being the cultural hub, is known for incorporating both traditional Armenian dishes and cuisines from around the world.
