Cookies as big as my fist, YES! If you’re looking for a Key West cookie, look no further. Mattheessen’s has got you covered. With every possible ice cream and milkshake options available if you something cool. But if you’re looking for a sweet cookie fix, they have chocolate chip, oatmeal raisin, and so much more. The lady working behind the counter was polite, friendly and busier than a one arm paper hanger. Please if you’re looking for an unforgettable experience, check out Mattheessen’s. You will not be disappointed, enjoy!

This is such an amazing place to grab an ice cream after walking around key west. Definitely one of the most delicious I’ve tried. Their cake batter ice cream was amazing. I would definitely return

Frozen key limeade. If you pass this up, you’ll regret it. Super refreshing on a rather warm day. We did a lot of walking (4 miles) and when we got back to the marina area, this was a welcome and well needed drink. Reasonable price and wonderful counter service. Plus, they have some outdoor seating to relax while sipping on the limeade.

Key lime pie was great, probably the best one we had in key west. Cuban coffee was good as well.

We ordered a whole key lime pie and one cookie. The cookie was soft and fresh, and the pie was exactly what we hoped for—bright, tangy, and well balanced. We first tried a slice at another location and liked it best out of the local competition, so we came back for a full pie for Thanksgiving. Great choice for a holiday dessert. The price is worth the pie, especially because of it's size.

When we first went to store, it was should have been open but the doors were locked. The lady inside waved gave hand signal as if to say just a minute. Well, we waited outside for at least 5 minutes and she never opened the door. We did go back hours later and she had opened for business. My great nephews enjoyed the ice cream. I love the way the store is decorated and it’s next to the best breakfast place ever; The Breakfast Club, Too.

I hesitate to leave this three star review because the pie was actually GOOD! Very homemade, very good. The first time we went, the lady was nice and she gave us that good pie, and I don’t want to take away from that. HOWEVER, the second time we went, there was a guy working the counter and he obviously wasn’t very versed in what to do. My husband ordered the key lime milkshake and after some hesitation, the gentleman scooped some hard vanilla ice cream into a cup, filled the top with ice and limeade and gave it to us, all for about $9 IF you don’t leave a small tip, which we did. If you are wondering if you read that right, yes you did. The guy didn’t blend the shake AT ALL. It was a hard ice cream lump with liquid floating around it. We were flabbergasted. How does one drink this? Or do we eat it? Yeah, it ended up in the trash with a lot of disappointment. Needless to say, we won’t be coming back.

Now that’s a cookie! Most oversized cookies suffer from the same issue - they are baked on the outside but by the time you get to the center it’s typically gooey undercooked cookie dough. Thankfully the chocolate chip cookie here was perfect. Baked throughout while still maintaining crunchiness on the outside but still cakey in the inside without being undercooked. This was one of my favorite cookies I’ve had in a long time.
