I'd give here a 3.5 actually. I came for a later afternoon lunch on a drizzly Saturday in April with a friend and her 4-year-old. I had no idea the place was so big inside and a "normal" restaurant, since I had been in the Irving Big Stop at the Canso Causeway, I thought it would be a smaller diner inside. No! Giant, pretty nice atmosphere with high ceilings, capacity for at least 100, a warm woody feel with a large artificial fireplace in the center, a section of baked goods for sale, etc. There was a lineup of about 10 people ahead of us, but it was no more than a 10 minute wait for our table. We were seated at a booth closest to the door, which normally I wouldn't love, but it was fine. The line-up persisted through the hour or so that we were there. Service was friendly but our food took at least half an hour to arrive. Luckily the 4-yr-old was distracted by his toys, so didn't notice. I decided to try their monthly burger platter (12.99 although I can't find a full menu online...it had bacon, cheese, a fried egg, lettuce, tomato and homemade patty on simple sesame seed bun) and wasn't too big, but was delicious. The paddy wasn't that thick, but again, just right for me and full of juicy flavor. The frozen fries were crinkled and fine. My friend tried their mushroom & mozza burger, but it had no sauce on it, so she requested a bottle of mustard to add to the bottle of ketchup which was already at the table. Her son had the kids' cheeseburger which looked the same size as the adult one, with just less fries on a smaller plate. To go, I got a slice of their chocolate cake with boiled icing and it was gigantic. I didn't even eat it until the next day, but liked it a lot. She got a slice of carrot cake to go, because her parents commented that they loved it, but she found it slimy and too dense, so didn't enjoy.
2nd visit: around 5pm on a sunny Saturday in July with my parents, and ended up getting the exact same booth as last time, closest to the door. We had a 10-15 minute wait to get in I would guess. We were told a group of 35 people showed up at once, and then left all at once, and then the regular tables moved quite smoothly. Friendly, funny waitor. I tried the "Big Stop Omelet?" which I don't see listed on their online menu, but it was pretty good, with bacon, mushrooms, peppers, onion, cheese...side of frozen home fries (too many, which I couldn't finish), and toast. My parents both opted for the Hot Turkey Sandwich and they said it was decent/average, nothing wrong, nothing memorable. Served with frozen crinkle fries and boiled carrots. The fresh-squeezed lemonade my mother found a bit too sweet until she stirred it, and then was ok with it. I loved it, and found it not overly lemon or sour. We wanted to try a dessert but were too full. While waiting for the food, we played a few rounds of the 'Original IQ' peg game which is at the table.
Although nothing special about the place, I'd still go back anytime. Mostly I want to try their coconut cream or lemon meringe pie, which are gigantic in the display case and I've heard are quite good.
