My wife and I were in the area in the early morning last week and decided to give the Heritage Diner a try for some breakfast.
I ordered a cheese omelet with some fries and mt wife ordered French toast.
Both meals were served quickly and were delicious. The portion sizes where just about right
I would like to come back to this diner because they sell some amazing Sour Dough bread to take home.
The staff here were all very nice and the price of the food was on par for the portion size.

Ever since I moved to this neighborhood, this place has quickly become one of my favorite spots. Every time I visit, the food is always delicious and the quality is consistently great. You can really taste the care that goes into every dish, and it’s the kind of place you just naturally keep coming back to.
On top of that, our server Nick was so friendly and attentive, which made the whole experience even better. I would definitely recommend this place to anyone in the area!

We have come to the Heritage Diner multiple times and were never disappointed. I was surprised when I noticed that I’d not left a review. The inside has three sections all equally comfortable. We sat in the room to the right of the register. It was quiet and welcoming. Lucille, our server was patient and helpful in answering all our questions. She checked in with us without being overbearing. The food was fabulous! I haven’t had a grilled cheese sandwich in years but they had a page in the menu with an assortment of options and pictures! I really enjoyed the creamy cheese and crispy toast. Plus, perfect fries. My husband’s salad was unique and delicious. Highly recommend the Heritage Diner.

The service was fine, the food was underwhelming, and the AI art plastered all around the restaurant was jarring. I was actually distracted from my meal by the creepy AI art of uncanny waitresses and unappealing food. I can’t understand why a real artist or photographer wasn’t hired. Also, the canvases don’t fit between the windows where they’re placed…horrible atmosphere.

Great diner with good food and a welcoming staff. The recent remodel looks really nice and gives the place a fresh, updated feel. The menu has also been updated with some great options, which we enjoyed. The only small disappointment was that the kids’ menu no longer includes some of the items it used to. Overall, still a solid spot with good food and service, and we’ll definitely be back.

Understaffed and poorly managed. This is the third time my family and I have tried this diner. We live within 5 minutes of the restaurant and hoped this would become a regular food destination. Unfortunately each time we’ve gone we’ve waited more than 15 mins once we were seated just to get a servers attention. Last time they were very crowded, so I understood, but today there were only a few customers. Our waitress (who I had to find) claimed she thought someone else had our table. This is poor management and not the fault of our server, but as I said, this is the third time this has happened.
Clearly management cares nothing about their customers because no one from the front walks around to refill coffees or check on their customers experience.
And a huge pet peeve of mine is the minuscule size of the cups they serve coffee in. Seriously? It’s like a dolls tea cup! Very cheap.
Our bill today was $88 plus a tip. Expensive for breakfast for 3 adults and a 2 year old. Suffice is to say we won’t be going back.

The staff is very friendly , the diner is very cozy and comfortable. The food is always delicious and the prices are very fair. I have been a customer since 2011 and have never had anything but pleasurable experiences.

Not a great experience Christmas 2025. The homemade sourdough bread, however, is outstanding! The menu was a bit minimal and offered no Christmas dinner specials. We got our soup in a regular amount of time and as it was served, were told our entrees would be right out. 40 minutes later, my son went to the front to ask them to please pack our meals to go… my younger son had worked all day and was exhausted and had enough waiting around. We all were ready to go before the meal even arrived! My son said no apology was offered when he explained how long we waited after having soup. A few minutes later our kind and apologetic server appeared and assured us it was being packed and would be right out- but they had no more mashed potatoes so they gave us baked (didn’t ASK what we’d like… just informed us.) The food arrived and some confusion ensued at the register as to where the check was… finally it was located and we paid and went home. One son received mashed potatoes with his salmon, my sister and I got baked potatoes with our turkey. My sister asked for her turkey with the gravy on the side… there was no gravy at all provided. My younger son’s burger had very wilted, half spoiled lettuce hanging off the bun all haphazardly. What a disappointing meal!
