Yakitori grill - I consider buying a small sized one - anyone with knowledge to share ?

I think this is right. In terms of burning charcoal with little smoke and being small enough to be conducive to tabletop cooking, yeah, very similar to others. One difference is no grill contact (skewers), but you can remove the grill from a hibachi, Lodge or small Weber, too, to perch skewers. The yakitori look more like furniture and don’t roast your face.
