"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!"
