Well that is so subjective to personal taste...
but it is great sitting out on the terrace when you want to have a really good chat with acouple of friends. The atmosphere is very conducive to losing a sense of time. It is very tranquil and relaxing... you feel like you have taken a step off the roundabout of hecticness. A respite from how busy and crowded life can be.

It is NOT the place to go to drink (unless you are rich)and make loads of new friends etc etc. It is a place to be cerebrally intimate.
