Anyone tried Chef Kwame’s Patty Palace in Barclays?

I was at the Nets games the last two nights, and this place was constantly empty. It's not in the best location, but also, one patty on coco bread with slaw is $19.50. Yes, that's similar to what you pay at the Fuku or Parm stalls, but it's still more… for one patty. I'll try it for sure at some point, but curious if ANYONE here has at any of the locations??
