paris restaurants with 3 teen boys
If they are like my sons, they will eat beef. Lots of restaurants have some sort of steak on their menu and they will probably especially like steak and frites. The crepe stands all over the city were also a huge hit with my kids when we were there in their younger days. Boulangeries also sell simple ham and cheese sandwiches on baguettes which should work.
Well there is everyone's favorite L'Entrecote, google them. Pizza is always good, Pizza Chic by ST Sulpice in the 6th and Pizza Grazie in the 3rd, though a pit pricy.
Casa Bini in the 6th for great pasta.
As the zedman_1 said, how picky, what do they eat? And price range? Do they eat pasta?
