Jeffrey's HamburgersB+

42 S B St, San Mateo, CA 94401 · Hamburger restaurant, Restaurant

Classic downtown diner doing thick, customizable burgers, crisp fries, and big milkshakes at fair prices; go for comfort-food satisfaction over culinary fireworks.

Our take

Jeffrey's Hamburgers delivers solid neighborhood dining through excellent burger quality and quick, friendly service, earning its grade B+ standing. Consistency shows occasional variation in burger doneness and bun quality, while the nostalgic retro setting provides comfortable appeal without destination-level distinction. Strong value and loyal local following make this a reliable casual choice for classic American comfort food, though it lacks the refinement or innovation to reach higher grades.

In more detail

The room channels a polished retro diner with warm and bustling energy: booths, a corner window seat, and staff who move fast. A typical note from diners: "Burgers came out quick and the shakes arrived overflowing." Expect friendly service and a neighborhood crowd near the movie theater. The cooking is classic American comfort more than experimental: thick patties cooked to request, crisp fries (garlic if you wish), and milkshakes that arrive with an extra tin. If you want chef tricks, look elsewhere; if you want a juicy burger on a simple bun with loads of toppings, you are in the right place. Families do well here. There is a kids menu, familiar foods like grilled cheese and hot dogs, and sides that kids actually eat. Shakes are a hit for sharing, and portions are generous, making it easy for families to split plates without fuss.
