Gravia is mine and the wife's favourite chill out place. We prefer mid afternoon where we will indulge in a mezze for two and cool half carafes of white wine. It normally ends up as quite a "session" on the drink but the nap afterwards refreshes us.
The only thing that irritates me are the strange guests that frequent the Gravia from the next door complex. The one where they do the strange chanting and they all appear to be hippie types. You can often see these people on a table for four/five, all on their own, glass of water, book in hand, her bag on one of the chairs, shoes thrown on another chair and her towel on another chair. Then an aquaintance from the same complex will wonder in, give her "friend" a cursory nod and do exactly the same thing with a different table. Thats two tables that could sit eight/ten taken up by these selfish people (normally girls). It really anoys me.
