Eat at a neighborhood restaurant or bistro. The menu, with prices, is posted in the window. Never order anything whose price is not known in advance. If you see selon grosseur (sometimes abbreviated as s/g), this means that you’re paying by weight, which can be extremely expensive. Avoid restaurants and bistros with English menus.
Delis and food stores can provide cheap and wonderful meals. Buy some cheese, bread, wine and other snacks and have a picnic in one of Paris’s great parks.
Lunch, even at the most expensive restaurants listed in this guide, always has a lower fixed price. So, have lunch as your main meal.
Large department stores frequently have supermarkets (in the basement) and restaurants that have reasonably priced food.
Street vendors generally sell inexpensive and terrific food.
For the cost of a cup of coffee or a drink, you can linger at a café and watch the world pass you by for as long as you want.
