Thats a good looking plate. I dont eat at Vietnamese places much, and I dont like those big bowls of Pho with meat which looks undercooked(!). LOL. But when I go with friends or coworkers, I stick to a platter of food like yours. I dont know what that cake slice thing is, but I get the platter of rice, salad, egg, grilled chicken, grilled porkchop. Such a good deal at about $17 CDN.
These places always price their dishes oddly. You can order a plate with rice, salad, one grilled chicken cutlet for $15, or order a platter with an extra pork chop cutlet and an egg for $17. Fuck, no brainer to me. I'll give you the extra $2 for so much more food! Mine will look somethng like this:
