Cosmo's Diner - Thorold

The food is exceptional and reasonably priced. The eggs Benedict were the best I've ever had! The crispy bacon was absolutely delicious! The staff was also very friendly.

My friend, and I both had an breakfast plate. delicious and served with a smile! the prices are very reasonable. atmosphere is cheesy! someone likes mearilyn and elvis!

Went for breakfast heat wasn't working ordered the breakfast special. Eggs came cold and runny... toast wasn't even buttered had to butter own toast with rock-hard butter. Place was filthy. Sign in the window States niagara's best breakfast... What a laugh and waste of money.

Great spot for breakfast! Never been disappointed! Always great service and food. We like the selection of breakfast and the price is very reasonable.

Normally I would enjoy trying a different restaurant but not this time. The diner was quaint and it did look well kept. The only issue was the food. I ordered the spinach and feta cheese omelet with choice of two sides and a coffee. My...two sides I ordered were baked beans and slices of tomatoes . The meal came out to much of my disappointment . The omelet looked more like scrambled eggs with spinach and feta and peppers and onions mixed in. My baked beans were nothing more than beans heated out of a can. The highlight of my meal were the three slices of rotten and mold infused tomatoes. I brought this to my waitresses attention and she apologized and asked me if I would like some new ones to replace the rotten mold infused tomatoes. I graciously declined. My bill arrived and the waitress said they took the price of my coffee off to compensate for my inconvenience. The sad part was the coffee was the best part of the experience. I hope things will improve for this diner because it could have a promising future.
