This place has some amazing cookies. Gourmet and worth the price (and calories). My favorite is the s’mores cookie and a pecan turtle one. So far no other place has beat their cookie quality. Mary's is the best!

Jun 13 · Tommy LeeWow... I mean... Cookie Crumbl has NOTHING on these because they actually sell real cookies. We bought 6 and got 2 free. You can bye editable cookie dough, gluten free versions, ice cream AND.... you can buy the premade dough to bake at home! Pairs great with Baron's Creek Wine...

My friends and I visited downtown this weekend and stopped by this store, and ended up walking away with 8 huge cookies!First of all, the staff were all super helpful and kind, the cookies are huge, and talk about delicious!I couldn’t resist, so I bought 6 and got 2 free and this is our 3rd day of having the cookies and they are still soft, moist, and delicious! I highly recommend stopping by!
Sep 26 · Victoria CheavensWhen you need a little treat to break up the shopping, stop in here and grab a yummy cookie. Lots of choices. Soft, chewy and big enough to share for only $4 although you probably want your own. I picked the dipped peanut butter.Service with a smile and helpful suggestions
