well,... mostly it is 100 additional points if 3 or more people...
we are usually only 2 so this benefit is worth nothing to me...
additional 10% on return visit is ok but also not that awesome....
best benefit i see is a complementary glass of wine *_*

any restaurant with a nice benefit ?
i only checked restaurants in Germany and Thailand so far..
