As noted, SPG Cravings has been replaced to some extent in Asia-Pacfic by "Marriott Members Dine More". This programme promises up to 20% discount for Plats plus 10 Marriott points per USD spent.
I booked a lunch at Saint Pierre at the W Kuala Lumpur tomorrow, which is listed as a participating restaurant on the MMDM website. I wrote to them to ask if the discount applied to the lunch menus. The response came back that "we are a completely independent restaurant" and as such, was not participating in MMDM and that they would check with Marriott as to why they were listed as a MMDM participant.
Someone here has clearly cocked up. It may be Marriott, I suspect it's more likely the restaurant. I've asked my Ambassador to please clarify the situation, as I'm clearly not going to get anymore out of the restaurant.
