This is a brilliant idea as well as rather realizable one. If you want to start new successful business I suggest the idea of weight-loss restaurant. Official social survey display that nearly 30% of population suffer from extra weight. The problem is rather serious and they can't stop to eat much. I think weight-loss restaurant or café will fix the problem quickly. Investments will scarcely be so big - this is first advantage. The guaranteed success here must be provided due to the following: you should offer at your weight-loss restaurant high quality low-cal dishes, use only best products. To attain sharp popularity of your weight-loss restaurant such factors as reasonable pricing and food quality are vital. As the idea author I recommend you to set average, prices but keep the dishes quality on highest level given that high-calorie and therefore expensive products will be mostly excluded from allowance. Engage in it instead a lot of vitamin-containing products
