This diner is right near my work so I thought I'd give it a whirl. Here's the pros and cons I experienced.
PROS: Tasty, tasty, tasty. Ordered a BLT on whole wheat with fries so that really could have gone either way (it's a middle ground, plain jane sort of order for when you don't want to eat anything too healthy or too bad for you haha). I've eaten a lot of tasteless sandwiches in my day, but this one was really good. The fries were deep fried fresh, so again, very tasty. Also, you get served quickly. Price was fair too: for my sandwich and fries plus a coca-cola, it came to $8.05. I handed the guy a $20 (but I didn't have 5 cents on me) and he gave me back an even $12.
CONS: It's a small cafe/diner. Very hot inside because the kitchen/grill is just behind the counter. Not a lot of seating and what's there is usually occupied by regulars who chat back and forth with the owners behind the counter. They are definitely much more friendly with their regulars. That's not to say they were rude but it all felt very rushed, like they wanted me out of the way so they could focus on chatting up their regulars. They were in such a hurry they almost didn't charge me and I don't think they would have at all if I hadn't stayed put and made sure they got my cash.
Worth going back? Definitely. The food has a homemade touch that gives it a yummy competitive advantage over generic chains like Tim Horton's.
