In reply to Eve.G:
Yup. We always go to grez if we can as it's nicer in many respects. Especially if the weather is marginal. Grez is a lovely sunny open grassy field
Musardiere can be a bit of a dank dingy hollow if the weather isn't good.
Facilities at grez are great with the key exception of the toilets. They're generally Turkish style. Or pans with no seats which really pissed me off.
PS count your change from the pizza man. He makes a fair bit on the side by short changing people deliberately and then acting surprised if you challenge him
