Camping in Paris

How is it that in Paris, the Mecca for all gourmets and food lovers, so few people own an oven? And the few who say that they do own an oven in fact own what I would call a toaster? The Parisian kitchens I have seen so far are an assembly of odd utensils and appliances that I would associate more with campsite cookout than haute cuisine. That must be why there are so many restaurants in Paris!
