As long as it's roasted to the point where you can squish it with a fork, it should be good. Just 1/3 the amount of garlic would be enough for me though.
While I agree with you, and I do dearly love garlic, I feel obligated to give you a word of caution:
If you eat too much roasted garlic, for the next 24-48 hours, every room you enter will smell like garlic, your sweat will smell like garlic, your farts (and there will be many) will smell like garlic, and your poop will smell like garlic. It will not be a pleasant experience.
Do you know if your body builds up resistance? This sounds awesome, but I don't want to get addicted and have to use larger and larger amounts of garlic :(
I'm pissed they wouldn't at least do a bit of fork smashing and spread the roasted garlic around. That shits gonna be falling all over the place. Terrible plating.
