I finally tried in-n-out and can proudly say I am a shake shack fan. I ordered the strawberry milkshake and grilled cheese sandwich. The strawberry milkshake made me want to go to McDonald for a mcflurry. It tasted so fake! As for the sandwich, this was the only thing on the menu that didn't have meat. It only comes with 2 slices of cheese so I request for double (a total of 4 slices) and ugh. People pay for this? I can make better grilled cheese sandwiches!
