Whether it is a buffet with pods or a cafeteria with pods, it sounds like it's going to be similar to RCCL and Celebrity in their similar venue. It's pods/stations set up each with various things (a bread station, a pizza station, a grill station, etc.) and you go from pod/station to pod/station depending on what you want.
Google
Royal Caribbean Windjammer Cafe or Celebrity Ocean View Cafe for an idea. It's a simple concept and much better than the line-up at Cabanas.
