"Our breakfasts were EXCELLENT. Biscuits and gravy was very tasty and the blueberry pancake was HUGE!! I'm glad we didn't order 2, we wouldn't have been able to eat it all. The last dish was eggs, ham, potatoes, and toast. The potatoes were cooked with onions and were delicious. Asked for the egg over medium and was cooked perfectly. We would definitely return for another meal!"

"Very nice little diner to stop for breakfast before crossing the border. Place was quiet at the time and the waitress was kind enough to get our order in before a large group to help get us our food at a good time. Parking out front was easy while it was quiet. Orange juice was really good too!"

"Main Street is quite depressed with many store fronts closed. Karen’s appears to be a bright spot. This is a diner, not fine dining (I do not believe such exists in the town). Staff are pleasant. The French fries were hot and perfectly crisped. My lobster role was decent. Sodas and ice tea come in plastic bottles so they do not brew their own. So if you want some of the basics, I would recommend this place."

"Really enjoyable local diner. We stopped for breakfast on our way out of town heading into Canada. The service was phenomenal and really friendly. Good prices, home-cooked food, we would definitely go back if we pass through the area again. We tried the corned beef hash with eggs and home fries/toast. Definitely delicious! They had real maple syrup to go with the ginormous pancakes, which were a little dense for me and a little light on the blueberries but still pretty good."

"A perfect cosy little diner if you’ve just crossed the border or about to! Fantastic portion sizes and very tasty homey food! Great value and food came out really quickly! Place was packed when we came in (due to them being pretty much the only place open in town on a Saturday morning) but our server still made a great effort! Couldn’t fault this place, great all around. Thanks legends!"
