"Fantastic atmosphere, great food and the Owner, Jay is a fantastic host. My wife and I had a late afternoon craving for pancakes and decided to give Diamonds a look. We weren't disappointed. I had the Grand Slam and my wife had the Diamond Special. Both were quickly, yet expertly prepared fresh. Looking forward to our next visit."

"If you’re looking for a place with good food & better people check out Diamond. Portions are huge, price is fair, & the people who run the place are the main reason to keep coming back. As you can see in the pictures, I recommend the French toast with fresh fruit!"

"Diamond’s is a classic diner! We stopped by for brunch for the first time and really enjoyed our stay. The food was delicious and the price was right; my eggs were cooked perfectly, and I would highly recommend the pancakes! The owner, Jay, is so kind, friendly, and he accommodated for my friend who has celiac. The atmosphere has your classic checkered floor, red vinyl seating, with 1950s pop icons on the walls, and music playing from a mini jukebox. We will definitely be going back!"
