Yup. I queried it with our Aris Meeha, since all the receipts from La Laconda showed the discount at the time of dining, but none of the others did. Obviously that's not the same as what's posted on the site, so maybe you'll have better luck. The irony is that there's more margin in the other restaurants anyway, so there's no obvious reason why the Bonvoy discount wouldn't apply in those.
