Ecological restaurants are also called greenhouse restaurants, sunshine restaurants, leisure restaurants, natural restaurants and so on. These restaurants are bred from planting greenhouses, and their characteristics are that plants, flowers and plants are planted or decorated in the restaurants, and various landscapes are built. However, the meanings of each name are also different. Greenhouse restaurant is developed on the basis of greenhouse, and its characteristics are that the temperature and humidity can be adjusted to the comfortable range of diners; Sunshine restaurant is characterized by taking sunlight as energy; Leisure restaurant has a wide meaning and does not clearly indicate the nature of the restaurant. The author thinks that among several names, the name of eco-restaurant is the most scientific and reasonable, which can accurately describe the personality of this kind of restaurant and is also the most promising and sustainable restaurant industry. Eco-greenhouse restaurant is a product of the perfect combination of modern facility agriculture and green catering. It is a large-scale greenhouse building with people-oriented, catering-oriented, supplemented by landscape. It integrates the lightweight, convenient and clear characteristics of greenhouse with the versatility of the building. The restaurant has a green natural environment and "miniaturizes" and "artistically" the colorful ecological landscape of nature. It comprehensively uses the knowledge of architecture, horticulture, facility horticulture, ecology and other related disciplines for planning, design and construction, and maintains the beautiful environment of the restaurant with facility control technology and agronomy cultivation technology, forming a plant configuration pattern with green landscape plants as the mainstay, supplemented by vegetables, fruits, flowers, grasses, medicines and fungi, and combining the landscape of rockeries, waterfalls, bridges and bamboo pavilions to provide green for diners. Safe and delicious ecological (organic) food adopts the sustainable operation mode of energy-saving, water-saving, residue and waste recycling and environmental protection measures, which gets rid of the limitation that the greenhouse is only used for planting in the traditional sense, and makes the greenhouse have catering function, ornamental function, leisure function, entertainment function, green food promotion function, energy-saving and environmental protection function.

Generally, ecological restaurants have a large space, far away from downtown areas, and the restaurants are divided and decorated by green plants or flowers, so the environment is quiet, and the diners feel that they are in a paradise. Some eco-restaurants are built in agricultural parks or farms with their own self-sufficiency in vegetables, fish and meat products. They can be cultivated (providing fresh fruits and vegetables for restaurants, leftovers for farming, and organic waste for biogas fermentation), cultivated (providing fish and meat products for restaurants and manure for biogas fermentation), restaurants (providing leftover food for farming, organic waste and wastewater for biogas fermentation), and biogas (providing high-quality fertilizer and water for planting). To realize the ecological mode of recycling, this park is helpful to promote social harmony and sustainable development, and should be a catering industry that should be supported and developed emphatically.
