The idea of a separate restaurant with sit down service for Centurion card holders is an interesting idea. I've never been offered the Centurion Card and in the past I've been skeptical of the value proposition. I certainly enjoy my Plat card. But, if AMEX were to have a number of these lounges internationally with a separate section (and with DL Plat level status) I might take a look. Having to spend 200K/yr on it though would be a difficult pill and even with business spend I would be falling short. Still, intriguing concept on AMEX's side.
