Mama T Parenti's Delicatessen is a straightforward, cozy deli tucked into Ontario’s West Philadelphia Street corridor, serving up hearty Italian-style sandwiches and classic comfort food with a homestyle touch. This mom-and-pop spot leans into tradition, offering a lineup that locals appreciate for its generous portions and fresh ingredients rather than flashy twists.

The vibe here reflects a neighborhood deli where familiarity counts. It’s the kind of place office workers nearby rely on for a substantial lunch — think thick-cut Italian subs loaded with quality meats and cheeses, like their Italian Sub or the Prosciutto Sub. Sandwiches come large and toasted just right to keep everything crisp without sogginess, which shows attention to detail that regulars clearly value.

Midweek evenings bring a different rhythm with Mama T’s Wednesday night spaghetti and meatballs dinner, ideal for anyone craving a classic Italian comfort meal beyond sandwich fare. The presence of carefully made desserts such as tiramisu and cannoli (with shells imported from Sicily and in-house cream) hints at a deli that carries tradition through every dish, not just the mains.

Visitors can expect a warm, inviting atmosphere marked by genuine friendliness from the owners, who take time to engage with guests and share stories behind their offerings like homemade olive tapenade for their muffalettas. This connection to authentic Italian-American flavors makes it stand apart from typical chain delis in the area.

  • Best for those who want a filling, no-nonsense deli sandwich and occasional sit-down dinners in a neighborhood setting.
  • Regular lunch crowd from nearby offices and local residents who appreciate fresh, well-made subs with an Italian influence.
  • Ideal times to visit include lunch hours for quick takeout or casual bites, and Wednesday evenings for a relaxed dinner with classic pasta.
  • The atmosphere is unpretentious and approachable, with a small-scale, family-run feel that encourages repeat visits.

Whether you’re after a big sandwich to keep you going through the workday or craving a homestyle spaghetti dinner toward the middle of the week, Mama T Parenti’s serves straightforward Italian deli comfort with an attention to freshness and tradition that locals in Ontario count on.

Yesterday was my first visit and will definitely not be my last! I love a great Muffaletta and they’re not easy to find in Southern California let alone 15 minutes from home in the Inland Empire. The owners were so warm and welcoming and we had a nice chat about this amazing sandwich. They make their own olive tapenade and it’s just as fabulous as Central Grocery in the French Quarter! I topped off my order with their tiramisu and it was equally as delicious as the Muffaletta! So glad I found you!

This is our go-to lunch spot, office around area. hands down the best sandwiches in town! We always order the pastrami with lettuce, tomato, and yellow peppers. Can never get enough of it. Love the toasted bread, perfectly keep it dry. A true tailor-made Mama T sandwich!

Felt like a NY deli. I got the Italian sub and it didn't disappoint. All of the meats and cheeses are so fresh. The cannolli shells are from Sicily and the cream is made in house, you can definitely tell. This food is definitely made with love. They have spaghetti and meatballs on Wednesday night that I've heard is very good so I'll be back to try it.

Cute little Mom and Pop type shop. It is take out only but so worth it. The sandwiches are amazing and perfectly made. The meats and cheeses are high end ingredients . I got the turkey and cheese and it was the best sandwich I ever had. I also got the rainbow pasta and it was delicious. The ladies are also very sweet and friendly. I will definitely be back for more!

The sandwiches here are fantastic and the people who run it are actual normal folks. The sandwiches and made with fantastic tasting meat imported from Italy and the prices and absolutely affordable for anyone. Far better than going to subway and the spaghetti dinner is 10 bucks on Wednesday. I went on Tuesday for the first time and then returned Thursday cause I needed to try the rest of the sandwiches and they’re all great. The Italian is hands down of the best you’ll get in the area.
