Nowadays, the catering industry is no longer a simple problem. The catering industry generally has a fast cash flow and a gross profit margin of around 50%. It should be said that doing well is better than doing well. The key points are as follows: first, we must choose the right port to open, and it is best to make fast food near business districts, pedestrian streets or large factories, colleges and universities (schools) with large passenger flow; Hot pot and barbecue restaurant are best selected in large communities and densely populated areas; High-end catering should choose relatively mature large-scale communities and business districts, preferably independent business buildings, and avoid choosing under residential buildings. The second is to find a good chef with authentic taste. The third is to train good waiters. Good service attitude, delicious food and moderate price will bring good business.
