My wife and I meet up with friends and had breakfast. Our service was great fast and friendly. The food was average. My wife did not like the eggs Benedict. She said the sauce did not taste like Benedict sauce. The pancakes are huge and the paper bacon is very good. I did not have an omelet but they look... More

On my to do list whilst visiting Colorado was breakfast in a diner, and this did not disappoint, helpful staff, prompt refills, great menu and a good choice of specials, not too heavy or greasy with a nice buzzy atmosphere

Great food! great wait staff! Great diner vibe! I love coming here, just don't do it often enough. I have come here for breakfast and lunch, and have yet to order something I didn't love. It's one of Prospect's gems.

We stopped here for dinner dining. We were greeted just at the door by a surly lady stating they were closed for the day. Their hours on the door stated that were open for evening dining. The claim was that they have changed their hours, but there was no posting on the door for a change of hours. We certainly... More

I had brunch here with friends and I have had breakfast here in the past. My veggie dog breakfast (eggs, home fries, veggie sausage and a pancake) was very good and the pancake was huge. Both times I've eaten here, I've had leftovers to take home. The sandwiches and burger that my friends had all looked good and they enjoyed... More

We ate there this evening. The food was good--not incredible, but pretty decent. Chicken fried steak was a little bland, but when I dunked it in my fried eggs with lots of hot sauce--tasty tasty. Prices were very reasonable. Homemade chips as an appetizer was a nice touch. I liked the ambiance. I'd like to go back sometime, order something... More

This is my go to place for the BEST fish and chips in Longmont. Nice atmosphere both inside and out. Great pies and the service is very attentive. The fresh potato chips for and appetizer is a plus! Someday I'll try something but the fish, but for now my fav!

This diner is actually in a tiny part of Longmont called Prospect. The breakfasts are wonderful, so I imagine their lunches and dinners are great too. It's tiny, but you can eat outside too.

Visited in the evening a couple of weeks ago on the reccomendation of my family who live in Longmont. There were six of us. We were away from our UK home for two weeks and this was easily the worst dining experience of the trip. We were seated at the far end and then ignored for about ten minutes. Eventually... More

Mistakenly thought it would be a burger and hotdog joint. There is a single hotdog on the menu, no chili, no specialty dogs. Ordered the burger, it was good and so are the house chips and French fries. Not sure it is worth the drive or the price, Whopper is just as good.
