I am a recent graduate of 2014, roughly speaking, the gross profit of the restaurant industry out there is around 30%, I don't think the profit of the school cafeteria is worse than that. College cafeterias are in short supply, why? Because the class time is relatively tight, so students know the principle of proximity. Detailed, the canteen materials are in the food market at wholesale prices, the chef in the hotel to do a good job on the end out, a good attitude, certainly profitable. Guaranteed to get rich. Hey. In short, you have to have concerns about doing a window and then consider increasing the window. I did not go to school this year, miss the cafeteria that, small seedlings window. Rice is delicious, dishes want to compare other windows delicious, the most important thing is that the attitude is good.
