Tried this place out, and sadly I wont be returning. Why?Product quality doesn't match with high price is the main reason. The homemade donuts at grocery stores are better. The chocolate covered one I got was so thin it was transparent and flaked off like sugar coating. The donuts were very wet on inside, and actually tasted better after sitting a few hours. Now.... I could overlook all the issues because they are edible, however, the price just doesn't match up with the product.There are a few other issues such as cash only, that can be overcame.But basically cheaply made donuts should be.. cheap. So either this place should improve quality to match the price, or lower price.

About and visit notes
Introduction / Overview: Your Go-To Spot in Alta Loma for Classic Doughnut Shop Charm
For residents and visitors in the Alta Loma area of California's Inland Empire, the search for a classic, no-frills, neighborhood doughnut shop often leads straight to K & M Doughnut. This local establishment is more than just a place to grab a morning treat; it embodies the nostalgic ambiance of a traditional "hole-in-the-wall" bakery that many Californians cherish. As a fixture in the community, K & M Doughnut specializes in fresh, daily-made doughnuts and a selection of other delectable pastries and desserts. It's a sweet spot that appeals to those looking for a quick, casual visit to satisfy their sweet tooth or jumpstart their day with a coffee and a pastry.
K & M Doughnut operates primarily as a doughnut and dessert shop, reflecting a focus on fresh-baked goods. Feedback from the local community is notably mixed, yet passionate. Many long-time patrons frequently praise the quality of the fresh doughnuts, singling out the variety and particularly highlighting the exceptional custard-filled options. Beyond the sweet selections, the shop is also recognized for non-doughnut items like its highly-rated muffins and its popular ham and cheese croissants, suggesting a broader appeal for breakfast and quick-snack seekers. Customers often comment on the competitive and reasonable pricing, finding the shop to offer good value for money compared to other similar places in the region. Furthermore, the business is known to be family-owned and operated, a detail that many locals appreciate, contributing to the establishment's community-focused reputation.
However, as a true local spot, the experience at K & M Doughnut is not without its unique quirks and challenges. Prospective customers should be aware that the shop is reported to be cash-only, a key piece of information for planning a quick visit. Furthermore, while many reviews speak of a friendly atmosphere, other reports indicate inconsistent service, with some customers unfortunately encountering rudeness from staff. Another important consideration for a visit is that the shop has a strict policy regarding animals, with clear signage indicating that dogs are not allowed inside, a point which has led to negative experiences for those with service animals. Lastly, the freshness and quality of the products can be a point of debate among patrons. While many tout the excellent flavor and freshness, others have expressed concerns about product consistency and pricing relative to perceived quality, recommending that products are sometimes better after sitting for a period of time, or that selection can be limited on certain days. Given the early closing times, especially on weekends, an early visit is often recommended to secure the best selection of the daily-baked goods. The establishment's casual setting makes it ideal for a quick stop rather than a leisurely sit-down experience.

For those who prioritize a traditional, family-owned shop aesthetic and are prepared for a straightforward transaction, K & M Doughnut is a compelling option in the Alta Loma/Rancho Cucamonga area.

However, a truly informed choice means acknowledging the key factors that differentiate this local business.

Secondly, while many patrons report a friendly atmosphere, there are documented instances of staff rudeness, which can impact the overall customer experience.

Finally, pet owners should be aware of the strict "no dogs allowed inside" policy, including for service animals, as indicated by explicit signage at the location and reported by customers. In summary, K & M Doughnut is worth choosing for a taste of authentic, reasonably-priced, and often praised classic California doughnuts, especially the fresh-made options, provided you come prepared with cash and understand the limitations regarding service and in-store policies. It's the quintessential, casual stop for a quick, sweet indulgence.

It was a cold day today, and I was out walking with my service dog. As I was passing by this place, I thought I’d stop in for a quick cup of coffee and maybe grab a donut to go. But the woman working there was extremely rude and started yelling at me to leave.There’s no sign or information saying dogs aren’t allowed, and I calmly explained that it’s a service dog and I just wanted to buy a coffee. She didn’t care and continued to be very disrespectful.On top of that, the shelves were almost empty—there was barely anything to choose from. Honestly, terrible service and not worth stopping by.
Apr 16 · Olena DmytriievaWe heard they have excellent ham and cheese croissants, so we stopped by for a few dozen to serve at a meeting. **HOWEVER** They only accept cash here. Well, my husband and I neither one had enough cash. SUPER disappointed they didn't say anything until my husband went to pay; no signage either. Poor business model in this day and age.
Apr 5 · Yvette M. LamaCOUNT YOUR CHANGE!!!!I was given change and didn’t think to count it… but when I added a TIP to the jar the counter lady stated”oh I under paid you $5” and gave me $5 back…. which I thought was strange.After getting into my car and counting the change including the tip, I was STILL short $5. So the counter lady withheld $10 when she handed me my change. This is so ridiculous!!! Trying to enjoy some donuts with grandkids and have to deal with this. This was first and last time visiting this shop!I will definitely be spreading the word to family and friends about this scam.
Aug 2 · K KDonuts are so delicious and fresh! Large variety of donuts including maple and chocolate bars plus ham and cheese breakfast croissants. Also huge cinnamon twists and donut holes with sprinkles! Yum!
