If you are one of the lucky people who are allowed to work away from their desk, taking your work out to a restaurant is not always a good idea. When you sit at a restaurant and work, you are not fully enjoying yourself and the food. Not to mention that you spend a lot of money. If food is not the issue, find another place you can work at, such as a common area or a couch in the building, where you would not need to spend money.
