There are four to an order, each about 2" in diameter. I'm not sure what your internal meatball yardstick looks like, but to someone who grew up with hand-packed Italian-style beef balls, these look downright bite-sized. The spheres arrive with fried shallots and an orange piquillo pepper sour cream sauce, which is phenomenal.
The balls themselves are fried to a dark brown crisp, forming a thin sort of shell. Bite into it, and it easily yields to the hot minced lamb meat within. The neck meat has been seared & braised overnight in a tomato/garlic/red wine solution, then combined with additional ground lamb & egg and fried to order.
You could crush each ball in a single big bite, but if you've got the restraint, the better move is to halve them and cover each piece with the excess sour cream sauce. Have at it.
