Request : The Keg Garlic mashed potatoes

Does anyone know the recipe for the garlic mashed potatos at the Keg? If you've ever worked there and know what goes into it, please let me know. If you haven't worked there, but have tried them and found a recipe that closely matches it, I'd also really appreciate it. I have tried a couple copycat recipes and something is missing but I can't put my finger on it.

Thes are literally the only mashed potatoes I even like and I can't get enough of them.

Thanks!
