I'm not sure I would like the chicken hearts, I went to a Brazilian restaurant a few months back and I tried one there and it was awfully chewy. Needless to say I couldn't swallow it and had to spit it back out on to my plate. I would just go with the grilled fish.
Do those grilled garlic gloves not blow your head off? That stuff is pretty potent. Won't be doing any kissing after eating one of those. Lol.
