I actually really like the festoon lights! Fairy lights remind me too much of Christmas to have as an all year round feature.

If you are using LEDs always choose warm white for domestic interiors.

It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!
