JUNK FOOD.
I think junk food that´s a good idea for 1 or 2 twices a month, for especials events... That´s very cheaper and with only one haburguer you are full. The service is very fast and easy but like all, they have some disadvanteges like they have a lot of grass in a long time, if you eat a lot of junk food you will have fat and you will have a big colesterol. To sum up, the junk food that´s bad, but if you eat only for rdpecials events that´s a very good idea.
