I absolutely loved Doug's Diner! It's such a great option if you're looking for delicious breakfast food with a little bit of a healthier twist. They have all the classic diner favorites, but there are also lighter, fresher options that don't leave you feeling like you overdid it. Everything we had was absolutely delicious, fresh, and full of flavor. I love that you can enjoy a good hearty breakfast while still making a little healthier choice. The food, atmosphere, and service was wonderful. Definitely a place I would recommend and will be coming back to! read more

My new favorite brunch spot up north! I used to live nearby and always wanted to come in, I regret it taking so long but I'm so glad I finally did! The food here is so good, and the staff is even more amazing. It's very homely, not a big chain and it definitely shows. Everyone is so nice, smiles all around and it's an all around feel good place. They have the breakfast staples but also some specials that are creative and delicious! We've had nutella crepes, chicken fried steak, breakfast burrito (which is massive!) and a special of the day - strawberry cheesecake waffle. All the ingredients come together perfectly and melts in your mouth! The one thing you HAVE to get is the cinnamon roll. Eat it while it's hot and gooey, you won't regret it! Next time I'm going to get the Salted Caramel Cinnamon roll. On Friday and Saturday they are open until 8 pm so you can enjoy them if you're unable to make it during the lunch hours! read more

Positive thoughts, first the cinnamon rolls are huge and eating them warm and fresh they are delicious. Negative thoughts next, there are onions in the hashbrowns. Wish I would have known that because I could have just ordered something different. Also it wasn't "a little onion" it was a lot. Even my husband who loves onion says it was all he could taste. Biscuits were dense and dry. Jam that went with the biscuit was more a runny sauce than a jam. Would I come back, maybe Price on the high end. Did order DoorDash so can't comment on ambiance. read more

I had never heard of nor been to Doug's before. Was nearby and look online to find something. Very excited to learn of this community dining experience. The staff is great. The menu is huge! Everything we ordered was delicious!! We enjoyed sitting outside. read more

I was visiting with a friend. We met a gentleman who recommended this place. Now we know why! Many foods made from scratch. When it's your first time, they FORCE FEED you a cinnamon roll. It was really good! Please force feed me more. Just a good down home cooking restaurant. We were there for breakfast. The best meal of the day. read more

Doug's Diner - Thornton - My basic breakfast, great griddle biscuit and cinnamon roll - Breakfast & Brunch Near Me - Thornton, Colorado

Unfortunately, today's visit to Doug's Diner didn't meet the usual expectations. I ordered a club sandwich and received two of the end pieces of bread, which was disappointing. The fries were also extremely short--many less than an inch--and appeared to be saturated with cooking oil, almost as if they had been fried more than once. We've had better experiences here in the past, but unfortunately, this visit just didn't meet the mark. read more

If you like coffee with breakfast, lookout! Doug's now charging nearly 5 bucks ($4.80) for a cup. I enjoy their food very much. Always delicious. But charging more than coffee shop prices for coffee will have me coming to Doug's less. read more

Incredible food and service! Comfortable cafe atmosphere with a huge menu and generous portions

Doug's is a quintessential diner. The staff is sweet and they spend time with you. The food is good and they offer a great variety. I have been a few times and the foods doesn't change, making it a reliable staple of the area. It has a simple look but has a quant family feel. read more

Food is good. Wait staff are busy and short with customers an a bit rude. I was there the other day and there was a waitlist as usual. I was with my handicap parent who had to wait in the car because their waiting area is small and not accommodating for handicap people when busy. They do have a strict "entire party must be present" policy to be seated--understandable. When my party was called I told them other party members were coming from the car and they did get an attitude. I did explain I have a handicap person in the car who could not stand in the wait area for twenty mins. The door person just dismissively nodded--didn't say anything. And then another skinny waitress (who has been there for ever) comes up a little hot asking if everything was ok. I didn't say anything and the other waitress said yes all was fine and indeed my mother came in and we got a table 5 mins later. Point is. The wait staff can be rude. Sometimes they come in hot and try to escalate situations. And their wait area is not handicap accessible when busy and they don't necessarily make people with disabilities, feel welcome. But again, the food is great! Prices are great and I will be back (maybe not with handicap parents). read more

Kenzie was AMAZING. She was super nice and checked on us frequently to make sure we had everything we needed. Service was really awesome and everyone was so nice. The food was really, really good. I got a cheeseburger with a side salad and my mom got a whimpy skinny papas with a side pancake. Pancake was soooo good and I literally have no complaints. They kept things moving even during the rush and the vibe was really chill. I would 100% recommend this to anyone in the area. I'm from out of town and I will definitely find a way to come back before we leave. read more

Good food and service just a little cramp on space at times feel like sardines in a can

I think this place is great. I've been here a number of times and each and every time it has not disappointed. The breakfast food is awesome, and their portions are huge so make sure you come hungry. They have a lot of great options from sweet to savory, to loads of meat, to eggs on eggs on eggs. My kids love this place as well which is a bonus because they tend to be pretty picky eaters. I've never been sad with what I've ordered but my favorite is most likely the Papas (Cowboy). read more

Wonderful experience! Shawna was an absolute sweetheart and made some amazing recommendations. The food was wonderful and came out quickly!

Visiting the area and searched for a place that is open before our family had to be at an early sport event. Doug's Diner is located in a large shopping center and has plenty of parking. Portions are large and pricing is great. The customer service with Kenziee was FABULOUS! Warm and friendly, she ensured our coffee was topped off and warm, our food came quickly, and that we got out in time to make our daughter's warm ups on field with leftovers and coffee in hand. Thank you Kenziee! read more

Good food, great service and great value for fresh food. Nice place for breakfast or lunch.

OMG!!! Looking to absolutely send you tastbuds to the moon? You have to come to Doug's Diner. I got the Colorado bison burger (locally sourced meat) and it did not disappoint. Was skeptical with the grape jelly on top but thought "welp, when in Thornton!" Perfectly cooked and super tasty. I would have paid 50$ for this burger. We also had the hillbilly breakfast, which came with a godly amount of biscuits and gravy, 3 eggs and bacon that tasted like a ribeye steak. Our serve Selena was very friendly and super on top of everything. You need to stop here if you're in Thornton/Denver area!! 1 million stars read more

breakfast with a Hispanic touch. Extensive menu. Good food, reasonable prices. recommend

Solid menu , great prices for a local diner in 2025 ! Food came out fairly fast as well. And I like that menu wise they do what they want and not what everyone else is doing. Almost reminded me of everything cracker barrells restaurant wanted to be . But just outshines them by miles flavor wise. read more

Great little breakfast and lunch restaurant. Portions are enough to share and service is friendly. On recent trips I had the BG (biscuit and sausage gravy), and Grandma's Hotcakes, both were delicious. Happy Hour is 3-5 PM and discounted non-alcoholic drinks, and appetizers are available. read more

This is a great brunch place in the area and worth the wait. We came in around 9:30 to beat the crowd. I do think they can fit more people in if they break up some of the tables since they don't really have two tops. Their staff is mainly friendly and helpful. The food is what makes us coming back. The food is fresh and homemade. The homemade jams are a must try along with the griddle biscuits. The side of tomato with the pesto was also really good, and a great alternative to more carbs. read more

Great spot for breakfast or brunch in Thornton! My server (Shawna) gave me a quick tour of the menu along with her recommendations and she gave great advice!

Came in with my son, servers were very nice but I ordered a small omelet and was given a large and also then charged for a large. Ingredients are pretty low quality, canned mushrooms, spinach didn't wilt in my omelet at all and the guac that came on the plate was not good at all. So clearly we didn't order well. Others around us seemed to enjoy the food and the home fries were good but the Sharon omelet is a miss flavor wise and I didn't appreciate being overcharged. Seemed very busy but weWouldn't return if we lived here. read more

Got the eggs Benedict - burnt English muffins (black) knife couldn't cut into the muffin. Told the waitress after I ate the first and was like I can't even eat this the muffin is so burnt and the knife won't cut - waitress goes you want a new one. I'm Like thinking in my okay cool at least 1 enjoyable half of eggs Benedict. She brings me out an English muffin only. So I got to put my cold dismantled egg and ham on the new muffin. Horrible experience read more

Very warm and welcoming first and foremost. The food is all homemade and delicious with a lot of different options. The inside is decorated with cute rooster's. I also love the views from the big window, it creates a beautiful ambiance when the sun is rising.... beautiful read more

Solid breakfast. Walked in on a Saturday morning around 10am with a standard 15-20 minute wait. By the time we left I overheard the wait was up to 40 min. Definitely worth a 20 min wait, probably not 40 though. Simple, no frills dining space with a small waiting area. Nice outside patio area as well but it was a little chilly so was not in use. Server was quick, attentive and friendly enough. Coffee and OJ was very good. I asked what kind of OJ they had, she said it wasn't fresh squeezed or anything but I wanted to try it anyway. OJ was cold and delicious, coffee was hot and better than most diner coffee. A sign read "HAVE YOU TRIED CINNAMON ROLLS?" so I had to try one. It was gigantic, came out warm and was delicious with our coffee. The icing wasn't overly sweet but had more of a sour (not in a bad way) flavor. Steak and eggs were good, pretty standard. Chilaquiles were ok but a little too salty in some spots due to the chips being seasoned. Side of bacon was definitely the star for me. Overall, pretty damn good. I can see why this place is so popular. Would try one of their specials if I make it back. read more

We went for the 4th or 5th time last week. There was a 30m wait but it was noon on a sunday. My buddy and I both got the turkey sausage burrito which were monstrous. My fiance got the carne asada papas and they were good. The only disappointing thing about the experience was I was too full to order their delicious cinnamon roll. read more

Amazing food, huge portions , reasonable prices, fast and friendly service. Go already！

Food: Was super yummy and hit the spot. To start with we had the cinnamon roll which was huge, and not exaggerating when I say this but probably the size of my head. It was sooo yummy though and we scarfed that down. The cream cheese frosting was soo good and ooey and gooey. For breakfast I had the Mona Lisa omelette, which was really good. It was a very large portion, which I appreciated since it was also cheap. The peppers, mushrooms, and bacon were a good filling. The hash browns were good too. English muffin I wasn't crazy about but other than that it was good. Service: Was good and very fast, food came out fast, and we were in and out of there. Ambience: I like it! It's a cool brunch spot with lots of funny signs. One that stood out to me was "I dream of a world where a chicken can cross the road without being questioned for its motives." Overall: A good reliable place for a quick brunch or breakfast, just make sure to plan ahead if you're planning on eating there on the weekends because it is about a 30-40 minute wait. read more

Food was great and service was 5 star! Live in Texas so can't come back as often as we would like.
