Just fantastic all the way around. Delicious donuts and pastries, affordable prices, and some of the friendliest people you'll ever meet. While all their varieties are delicious, I have to give a special shout out to their fried apple fritters! Good Lord they are good! Imagine someone taking the inside of a homemade apple pie, you know almost all sliced apples and little filler, and then rolled in with some delicious donut batter. Then tossed into the fryer to become crispy and golden brown, with all the crunchy edges you could want, then topped with a light sweet glaze. Sure it might stop your heart, but it wouldn't be such a bad way to go for this bad boy! Anyways, like I said, it's all delicious, won't break the bank, and all served up by some great kind folks. Definitely check this place out! Cheers! read more

National Donut Day and the glass case was empty. The fresh donuts coming out of the back tasted day old at best. The employees were kind and friendly apologetic for the wait for the glazed donuts. Too many other options for donuts within a 3 mile radius to drop another $15 on a dozen hoping they are better. read more

environment is amazing, owners are so accommodating, donuts are the best i've had in the south county area they're fresh and i give the food 1000/10 read more

I saw a Facebook post that they had old fashion donuts yesterday morning so my husband went to get a few. They were pretty picked over by 9am, but he got a few to try- long Johns, glazed, old fashioned, and an Apple fritter. I will say we usually drive o er 20 min to our favorite donut spot that wins best donuts in STL yearly, but we had hoped to find somewhere as good close to home. Unfortunately, Shamrocks didn't meet the mark. The donuts were ok, but they lacked the freshness we were used to regardless of the time of day we buy them. The donuts were just dry. I tried bites of each one and the only one that wasn't dry was the apple fritter. The abundance of apples definitely helped with that moisture I know they often have some fancier donuts so maybe we will try a few of those in the future, but we won't be back for the standards. We threw them away after a few bites. read more

Shamrock Donuts - a variety of doughnuts in a box - Donuts Near Me - Arnold, Missouri

CELIACS!! DO NOT GO HERE. We ordered ahead because we were told the donuts were completely "gluten free" They even showed us that they were made on a separate side and with a separate fryer. But NOT CELIAC SAFE. Had the worst reaction after eating them read more

Taste, presentation, price, service: 10/10 I do wish that there were signs to give you an idea of the name/flavor of the choices but that's okay because the person working the counter was super friendly. They made the sandwich on the spot and were super fast. Definitely worth a visit! read more

Can not recommend enough. We stumbled onto it from Arnold ball fields. They start making at 6 the night before. All made from scratch and reasonably priced. read more

Shamrock Donuts - a display case filled with different types of donuts - Donuts Near Me - Arnold, Missouri

They ask you to call ahead to have breakfast sandwiches made. When you call, it rings 20 times, no one answers ever. Then you go there to order because no one answers the phone ahead of time and they are rude because you didn't call the order in!! No thanks! Bad service, mediocre donuts. read more

Love the quality and variety of donuts at Shamrock Donuts! Also love the hot breakfast items that they offer the later half of the week.

Delicious donuts (especially the chocolate-cream filled Bismarck!), great variety, friendly people, good prices, and a special offer for first responders and military = what more could you want? Shamrock Donuts is our lucky charm when we are in Arnold. read more

Best donuts hand down and the owners are very polite and the staff is amazing. My favorite donut by far is the Persian roll

Now I love donuts and even try to go to little shops on vacation but it is hard to match the friendly atmosphere you will get here. They are always trying new things and making sure to create fun for their customers. Highly recommended!! read more

Only donut shop I found open in Arnold on a Sunday. Very little selection choice. Very taste what we were able to try.

Very friendly donut shop with a great variety. They have plenty of seating which you don't find much in a donut place. I loved the salted caramel long johns and their old fashioned are amazing. read more

Shamrock Donuts - Donuts Near Me - Arnold, Missouri

This place has THE BEST donuts in the whole STL and surrounding areas. (At leash that I've tried, and I've tried a lot of donuts!) Anytime one of my friends/family try them, they can't get over how good they are! They do sell out quite early on saturdays and sundays - beware! But they even offer you to make an early order with them before Saturday to pick up in the morning. Or even a standing order! They have always been super friendly and this will continue to be my go-to place! read more

This place is addicting! We try to go at least once a month (id love to go more but I'm afraid I'd gain too much weight ). I am in love with so many of their donuts- apple fritter is the best ive had, old fashions I hadnt tried before this place but they are my new favorite and i absolutely love them with coffee, and my regular has always been a long john with caramel or maple, and these are a must from here! It's such a cozy little place & i always feel at home in here for some reason. What a great business in so many ways. Nice staff, super attentive, definitely take good care of you. Take a tip from a loyal customer- we've woken up SUPER early just to get there before everyone else, especially the big weekend crowd. Their donuts are THAT good that you can roll out out of bed if you want a wide selection. If you snooze, you lose! Someone else complained on here about this and was super rude, ummm who's going to get donuts at 11? It isn't food that can be saved for the next day... read more

Overall I enjoy this shop very much. The doughnuts are so fresh and so good and the variety is great. The doughnuts usually stay fresh for a couple days after we get them home so you can snack on them later, which is awesome. However... I feel the people working sometimes aren't the friendliest. Sometimes the vibe is slightly off putting... but maybe it's just me. Certainly doesn't stop me from going but it is a bit odd. Also, you have to get there before the sun comes up if you want to get the full selection. I am super glad they're doing so well but... mayyyybe make more???? read more

Sent my son up to Shamrock to get a half dozen donuts, this Tuesday morning at 9:10. He ended up going to another donut shop because Shamrock was pretty much cleaned out. I know they have a good business, but at 9:10 am and cleaned out of donuts is not good business read more

The donuts were fresh and delicious! Terri waited on us and could not have been more friendly or helpful. I had never had a double glazed chocolate chip donut before and let me assure you it will not be my last. Oh my! The old fashioned are so yummy. So glad to find a new favorite donut shop! read more

First time going there and the breakfast sandwich was amazing. The guy behind the counter was so welcoming we will be going back! Best place for breakfast I've been to in a long time! read more

Apple fritters were fantastic . Never had any thing like those! And I'm not a donut person . They were great! And the bacon donut was fantastic. They also use Soy oil for a more better healthy donut! read more

Theses are not the best donuts I've had but I don't think they are the worst either. I wouldn't recommend them to people I know as there are better donut places around. The chocolate on the long John's tasted like cake icing in the tub from the store and the "Cinnamon Rolls" were really just a bigger version of the cinnamon twist donuts. read more

The Arnold area has needed a good donut shop for so long and now they finally have one in Shamrock Donuts. The donuts are light and fluffy, not greasy or heavy at all. There is a great selection of classics but their specialty donuts are where it's at; we tried a Cinnamon Toast Crunch, cherry cheesecake and banana pudding donut and all were very tasty. There was a line out the door when we got there on a Saturday morning, as it would benefit from having a label or name for the many different donut types so there weren't so many questions from customer. With that said the line still moved relatively quickly. We will definitely be back! read more

Two words: apple fritters! Perfectly crispy on the outside, soft on the inside. Everything else looks great. I just can't get past the apple fritters! read more

Can I offer some advice? As a parent of a peanut/treenut allergy kid, nearly every bakery and every donut shop is unavailable to us. We heard that Shamrock Donuts was nut free and went there with the whole family excited to, for the first time in years, have donuts as a family. Alas, they have pecans on one donut. They said they sometimes fall into the glazing machine so don't get anything glazed. So disappointing. HUGE OPPORTUNITY MISSED: Shamrock Donuts - get rid of all the nuts, clean all the equipment and start advertising yourself as Peanut/Treenut free - get that on every add and put it on facebook - ask us to spread the info - you'll be making a killing in no time. read more

No heads up there is an extra charge for using a card when I told the employee it was my first time to try the donuts. There goes my tip. Had no idea a business did this if spending over $10. Very annoyed. read more

Extremely clean great donuts. Family run and operated and friendly too. Our church members at City On A Hill love em.

I bought choc long johns and because of the icing my grandson wouldn't eat them. It's to much like a cake icing would rather have a choc glaze. But they were very clean and friendly. If they would change the icing or give the glaze a second choice I would go back. read more

If I could have given them no stars, I would have. Gloves were not worn in. The making and topping of any donuts. I watched the employees handle the donuts while spreading chocolate and various other toppings WITHOUT GLOVES! I mentioned it to another employee and was met with attitude from the manager (only guessing). She told me that they wash their hands constantly. I watched them touch handles, countertops, the divider to to front of the shop and then the pastries. This is serious contamination. read more
