Offers in tourism that are being developed based on the preferences, wishes and needs of potential and actual visitors result in the growth and development of travels throughout the year. By developing selective tourism areas we can prolong the tourist season, develop tourism in less developed areas with unused potentials and attract tourists of higher purchasing powers. For the purpose of getting to know the wishes and expectations of tourists it is very important to do continuous researches in order to collect information on the basis of which strategies could be made for potential attracting new market segments or creating loyalty with the existing ones. Gastronomic tourism is a selective type of tourism where the decision to visit a particular destination is at least partly motivated by an interest in foods. Croatia has experienced a growth in the sphere of gastronomic tourism in the last decade, which has been clearly shown by the results of the TOMAS survey on opinions and spending habits of tourists in Croatia where guests have rated gastronomy as a significant motive for their choice of the holiday destination. Gastronomy has been a part of Croatias tourism promotion for many years creating an image of a country with a broad original high quality gastronomic offer. The growth and development of this product is based on the rich gastronomic tradition and the growing number of gastronomic facilities with a top offer of local specialties. This tourist product is best developed in Istria, followed by Dalmatia and Slavonia. The main activities aimed at the development of gastronomy tourism in the Croatian strategy will be the inclusion of gastronomy offers in world gourmet guides, branding the national and regional gastronomy offers, the development of educational programmes for a broad interested public and the facilitation of connections between local food producers and the hospitality sector. Marketing mix is a combination of tactical marketing instruments (product, price, distribution and promotion) managed and combined by a firm in order to produce the desired reaction on the target market. The increased demand for gastronomy tourism is partly the result of an increased promotion through specialized TV shows, specialized magazines, radio shows, culinary blogs, web sites and gastronomy manifestations. Gastronomy manifestations as a specific type of marketing activities promoting local products contribute to an increase of the number of visitors, to the prolongation of the tourist season and a stronger promotion of the specific destination on the tourist market. The advantage of these manifestations is communication going on "face to face". In this way a contact is made with the existing and potential buyers, synergy becomes stronger between producers and exhibitors, visitors and local community. The manifestation "Truffles Days of Buzet Area" has helped the development of the town of Buzet, has raised its image on domestic and foreign market thus making possible entering into new partnerships. The aim of such an event, besides publicity and realization of economic results, is primarily to familiarize the society with the products of the local people, with their gastronomy and autochthonous specialities and traditions of the region.
