Worst food ever

A friend and I went last weekend for a fountain Pepsi and she had cherry pie. Worst experience ever. The pop was FLAT, they offered me something else so I chose Lemonade. How can you mess up Lemonade but it was lousy. Tasted like a cheap powdered mix. The CHERRY PIE was THE WORST EVER. The crust was SO HARD that you couldn't cut it with a knife. My friend quipped she could use it to take home to hold her window open it was so hard! like it had been reheated a few times. The filling wasn't even real cherry pie filing, it tasted like JAM!!!!!! just terrible We asked if they were under new management as we used to like going there, and sure enough, since last year it's changed management. The old owners had run it so well and the food was good. Too bad. Also, the floor was filthy and so was the grill. I would never go back there again....

Mediocre food, Poor service in an area with far too many better options

1st (and last) visit today. The diner atmosphere is ok, the service was pathetic (was clear the server had no interest in listening to our requests or remembering what we'd ordered). Burger was solid, "home fries" were revolting. In an area with a zillion places, the Mars shouldn't even be on your list.

Decent Eggs Benedict

Mars uptown is a classic diner with a twist -- it's got a fun mars / space theme to the decorum, and overall it's well kept, clean, and above average of what you can expect from the traditional greasy spoon type diner. I ordered the traditional eggs benedict which came, as excpected, with two poached eggs, on english muffins, and peameal bacon, with some potatoes and a slice of orange. Overall the presentation was good for a diner. The orange was sliced in twist and nicely displayed, the eggs benny were artistically smothered in hollandaise, and the potatoes looked greasily tastilicious. So how was it? Well those benny fans among us will know how difficult it is to achieve the perfect benny. This was not perfection, but was above average, decent in every way. I'm still on the search for Toronto's best eggs benedict, but if I had to go back to Mars and have another I wouldn't lose any sleep over it. So first of all the waitress asked how I wanted the eggs poached -- a good sign. If they don't ask you know you're in trouble. Unfortunately, even though I asked for medium poached I got one medium and one hard egg. Not a meal breaker, but still not so great. The hollandaise sauce was a little on the gelatinous side, but was flavorful, so I can forgive the consistency. It wasn't the best hollandaise I've had, but it certainly wasn't the worst either. The peameal bacon on the other hand was awesome. I'm actually not a big fan of the peameal (I prefer standard), but they did it right -- grilled to perfection, and the slice thickness was just right too. The english muffins were the standard affair -- toasted too lightly for my liking, but I don't get in a knot about the muffins unless something is terribly wrong. The potatoes looked and smelled amazing, unfortunately they failed to deliver the same oral "oomph" that they give upon the first visual inspection. Maybe more spices would do the trick, or add in some cheese. They were fine though, it's not like I didn't eat them, I just wasn't wowed by them. As for the service, nothing to complain about. The service was actually quite good considering the diner type atmosphere. Warm, friendly, adequate in speed. So, to summarize, Mars is a decent diner with decent food at good prices. I wouldn't hesitate to go back if someone else wanted to go or I was hungry and passing by, but I'm definitely still on the search for a really killer benny in Toronto.

Mars attacks with massive portions at fair prices. The Spring Benedict with avocado and Swiss cheese and the Corned Beef Benedict are unique takes on the classic brunch dish. Hollandaise goes on anything you like, including the pancakes. Visit on a weekday to avoid the weekend rush.
