Welcome to sandwich heaven! First time I came to this place was right after work. It sits in the middle of Waterloo’s “Loo” downtown. I got my usual, the regular Italian, and I was more than happy with it! Fresh bread, crisp veggies and a nice amount of layered meats! If anything, would have asked for an extra side of oil and vinegar. Now where this place went really out of control was when I tried their other sandwiches. I got a turkey club which was probably the best club I’ve ever had and their “tri-tip” sandwich which I couldn’t get enough of. Sliced, grilled delicious beefiness. There’s also a very highly rated pizza place right down the street, but I haven’t managed to get there because whenever I am in Waterloo I come straight to Mamas and get 1 or 2 sandwiches! I I just, really love the place.

We tried another new place for us , Mamma's On Mill. The sandwiches we got were excellent. Some of the better sandwiches that we've had in a while. The place is pretty small inside & their fountain soda machine was broken , but the sandwiches were top shelf. We will be back for sure..

I’m a sucker for a good sandwich and this place has it going on. Walking in the door I was immediately greeting with smiles and a, “what can we do for you?” Just good vibes of the jump. I ordered the Big V-8 16” thinking, I’ll eat half now and half later. No. I ate a quarter of this monster and I’m sweating. So much meat. The bread is delicious, the meat has healthy portions and tasted amazing. I’ll be back here again for sure.

Came in on a Monday around 12:15pm. Was promptly greeted and order taken. These guys have a wide variety of hot and cold sandwiches, fountain drinks & assorted chip options. Quickly got our food, and found an open table (1 of 4). Sandwiches were all consumed quickly. Tri-tip sandwich was my favorite with the spicy mayo! They have a cool but gigantic puzzle on the wall (of the world) that supposedly contains over 60k individual pieces and took them over a year to put together. Kids really looking at this.

The sandwiches our group had was Spicy Italian, Grilled Chicken Fajita, and California Turkey Club. We all were very pleased with how delicious they were! My Cali Turkey sandwich (on toasted marble rye with provolone cheese) was the best turkey sandwich I've ever had!
