164 S B St, San Mateo, CA 94401 · Steak house, American restaurant, Bar

Classic steakhouse with standout dry-aged steaks, lively service, and showy table-side desserts; pricey and occasionally uneven on sides and hospitality.

Our take

Porterhouse earns its A- grade through exceptional dry-aged steak quality and knowledgeable service anchored by memorable table-side dessert showmanship. Reliable execution across most visits supports its loyal following, though occasional inconsistencies in sides and modest spatial comfort prevent grade A territory. A solid neighborhood steakhouse that delivers on its core promise.

In more detail

The room feels warm and bustling with classic steakhouse energy, white plates, and the occasional flash of fire from table-side desserts. Service is often attentive and knowledgeable, with quotes like "our server guided us to the right cut" balancing a few tense reports when policies are challenged. Steaks draw raves for dry-aged depth, while sides can be hit or miss; several diners highlighted Bananas Foster showmanship as a memorable finale. The kitchen leans elevated-traditional rather than flashy, a classic steakhouse approach focusing on in-house dry aging and well-executed staples. Expect carpaccio, tartare, ribeyes, and porterhouse with sauces like Bordelaise or Bearnaise, plus salads and indulgent sides. The culinary approach leans elevated traditional: quality ingredients and technique over avant-garde twists. Families will find enough familiar options—steaks, pasta, mac and cheese, and simple sides—to keep most kids comfortable. There is no explicit kids menu in the data, but portion sizes allow sharing, and plain sides like whipped potatoes can help. Noise can rise at peak hours, so early bookings may suit families best.
