I have eaten at Mars on occasion because very few places in this town do all-day breakfast, but always knew it was kind of low-quality food and I would never take another person there.
However, I just ate there today again for the first time in a year and WOW it has dramatically improved. The new sandwich section is a HUGE improvement over what was there before.
I had the steak sandwich, and was pleasantly surprised to find it on a homemade foccacia bun. The only bread I've ever seen there before was white or brown from No Frills. It was seasoned with horseradish mustard, sauteed veggies, and was a great sandwich all-around. The other lunch choice was a turkey club and I saw it being delivered to a table; it looked awesome.
Best of all I got the 50% off lunch special so it was only $5.50 + tax. What?! What has happened at Mars, I wonder. The girl who rang me up said they are trying to improve the menu (for what I am sure is the first time in 20 years.)
So if you have written off Mars, give it another shot. The interior is still kind of gross (think American luncheonette with none of the charm) but I hope this is the start of a turnaround so they can echo the rapid changes on College St. while still keeping the same low prices.
