Terminal 2 has a lot of places to go to. I could not recommend one more than the other. Just stay away from salads, though. What you are getting cannot be called salat, especially the dressing. Stick to more typical french sandwiches with fresh baked baguettes. The ones with smoked ham or cheese are just great. There is one place (I forgot the name) that looks like a bakery, where their products are quite good. They have more than one outlet.
Good luck
