At M Sandwiches, we specialize in freshly made, authentic Vietnamese bánh mì. Every sandwich is crafted with care, using high-quality ingredients—from our house-made pâté to freshly grilled meats. Our simple, focused menu highlights the best of traditional Vietnamese street food. We offer classic favorites like Grilled Pork, Beef, and our take on the original banh mi. Each sandwich is made fresh to order with balanced flavors, crunchy pickled daikon, and just the right kick. Whether you're grabbing lunch or looking for a quick, satisfying bite, M Sandwiches brings bold, fresh flavor to downtown San Mateo. Let us show you how a humble sandwich can be something truly special. M-Sandwiches opened its doors in August 2017 with one goal: to bring authentic French-Vietnamese bánh mì to downtown San Mateo. While many locals knew and loved this iconic sandwich, it was hard to find in the area, so we decided to open a small shop focused entirely on doing it right. Our mission is simple: take a humble street food and elevate it using the most authentic ingredients and time-tested techniques. Our menu features many delicious classic bánh mì options. Thank you to all our local customers for your incredible support—especially over the past year. We’re proud to be part of this community.
