I found Mary's Mountain Cookies online when searching for a place for a friend and I to meet at Park West. It took her son and I almost 15 mins to decide on one item each to order. The mouth-watering options made it very difficult, so I asked Iris, the kind and personable lady behind the counter and she helped me narrow my options down to three.

I'm not big on chocolate, but every morsel of the Toasted Brookie I got was worth the additional calories...

Cookies were a bit more expensive than I was expecting. Cookie maker had an amazing attitude, she was very poppy and had a great way of engaging with customers from her station. Cashier seemed a bit tired but still had a smile on.

These are the best cookies I have had in a really long time they’re like homemade but they’re huge. They’re so delicious and the staff is so friendly oh my gosh it makes you wanna go back over and over.
