How to find a cheap lunch anywhere.

Never eat near a telephone box! Telephone boxes are found in tourist areas.. where good food goes to die. If we really must do so then it should be a national chain such as McDonald's.

On the other hand It is nearly always better to go to a non branded outlet for lunch if you are in a business district. Such an outlet needs to have standards as a bad reputation spreads quickly in an office. They cannot afford to disappoint.
