About This Spot

Stepping into King Calamari feels like uncovering a quiet gem nestled within the heart of Union City’s everyday hum. This family-run Chinese kitchen emanates a comforting warmth, where time slows just enough to savor the simple joys of good food and genuine hospitality. The space itself is modest, unpretentious—a place where familiar faces might chat about the day’s happenings while waiting for their favorite dish to arrive.

The mood here is calm but lively in its own right, punctuated by quick, attentive service that manages to be both efficient and personal. There’s a sense of steady rhythm, with kitchen staff working deftly just beyond view, and the subtle promise that your order will arrive thoughtfully prepared and just right—never rushed, never overdone.

What draws visitors back again and again is less about an elaborate menu and more about the experience embedded in the food. The crispy calamari, for instance, carries a distinctively light crunch that remains even after the meal has settled in at home—a testament to the exacting craftfulness behind the scenes. Paired with a house-made vinegar garlic sauce or a touch of jalapeño heat, it’s a flavor memory that lingers gently, inviting quiet conversation and perhaps, another taste.

King Calamari is one of those local places where the food speaks in subtle layers rather than bold declarations, and the care in sourcing fresh California calamari shows in every bite. It’s not just about filling a plate but offering something that feels like a small celebration tucked into the routines of daily life.

Whether stopping by for a solo order or gathering a small group, the atmosphere quietly encourages connection—between the people who run the place, those who come to eat, and the shared appreciation for a meal made with time, tradition, and a welcoming heart.

I always order the single size which is the size of a togo styrofoam box for $16.99 whenever I am in town. It's very crispy and still crispy when I get home and even after a few days in the fridge. It goes well with vinegar. It's very addicting.

Tucked away in the hood of Hayward, you’ve got this lil nice family run restaurant that’s out of this world! The customer service here is unmatched to the point I thought I was a in michelin restaurant. The chinese cashier makes sure your food come out piping hot and deliciously fantasia. With the flick of the wrist and the spin of the heel, your food comes out in the blink of an eye. And now that’s what I called customer service

Signature Chefs Crispy Calamari is the only place I will order the party tray from. Chef boss insists using California sourced fresh calamari to make his signature dish. Dipped in their vinegar-garlic sauce~ can't eat just one!

Dropped in first time today. Review is very positive. Tried the soft calamari and really good. Crispy one is a bit too hard for me, both are worth a try. The portion is large, recommend.
