What is the Best Hamburger in San Mateo?

The best hamburger in San Mateo is widely considered to be at Jeffrey’s Hamburgers for its retro diner authenticity, while Jacks Prime dominates the gourmet category. Our 2026 review ranks these spots based on beef quality, searing technique, and flavor consistency.

Here is what we found during our taste tests:

Jeffrey’s Hamburgers
This is a local institution. If you want a burger that tastes like a memory of the best 1950s diner, this is it. The patties are thinner, cooked on a flat top for a great edge-to-edge crust, and served quickly. It is affordable and consistently delicious.

Jacks Prime
For those seeking a thicker, juicier bite, Jacks Prime uses organic, sustainable beef. The flavor profile is deeper, more akin to a steakhouse burger. The buns are sturdy enough to hold the juices without disintegrating, which is a crucial fail point for many other spots.

The Refuge
While technically a pastrami shop, their burger is a heavyweight contender. Topped with their house-cured pastrami, it offers a salty, savory umami bomb that you won't find elsewhere. It is heavy, expensive, and absolutely worth it.

Comparison: Which Burger is Right for You?

Choosing the right spot depends on your mood and budget. Here is how they compare:

How to Make the Best Hamburger at Home

I used to think my backyard burgers were good, until I realized I was essentially steaming them on a standard grate instead of searing them. Once I switched to a solid surface that could hold massive heat, the difference in crust and flavor was immediate.

You can achieve the same quality as Jacks Prime or Jeffrey's at home, but you need to abandon the wire grates.

The "Searing" Technique

This is where Arteflame Grills excel. By using a solid carbon steel cooktop, you eliminate the issues of standard grilling. Here are the benefits:

1. 1,000°F Sear: The center of the Arteflame cooktop reaches over 1,000°F. This instant heat creates a Maillard reaction (browning) that locks in juices immediately, rather than drying the meat out over open flames.
2. Grill All Food at Once: You can toast your buns, caramelize onions, and crisp up bacon right next to your burger patties. Nothing falls through the grates.
3. Flavor Retention: Because juices don't drip onto coals and cause acrid flare-ups, the burger tastes like pure beef and fire, not burnt grease.

Pro Tip: If you are looking for high-quality meat in bulk, you can always visit the Costco in Foster City or South San Francisco. Buying fresh ground beef from Costco is a solid base to start with, but you can elevate it significantly by grilling on your Arteflame Grill or using the Arteflame Grill Griddle insert on your existing Weber or Green Egg.

Why We Call It The "Social Grill"

An Arteflame grill isn't just for cooking, but it changes how you host. Its round design invites friends to stand around the fire rather than waiting on the patio while you cook alone against a wall. It turns the act of grilling into a shared social experience, similar to a Korean BBQ or fondue, but in your own backyard.
