Tadamasa: Indulge in Unique Ramen Creations in Union City, CA

Tried Tadamasa's tonkotsu ramen and loved every ingredient including the chewy bamboo shoots, perfectly-cooked noodles, and flavorful egg. The menu also extends to items such as the coconut miso ramen and black garlic oil ramen. Interior feels warm, casual, and clean, and the owner is super chill. If you're in the area, do give this place a try!

Cute little restaurant. Environment is good. Thought to go an ramen restaurant in this raining day. And this place came to yelp. Ordered 5 ramens and they all tasted good. The main reason I gave a 4 star is the payment. We asked them to split the whole check into 2 and they were little reluctant. They put 18% tip on my receipt and it’s hand written. It’s like someone made a decision for you already. Didn’t like it..... Nice for a raining day

Best Ramen in Bay Area hands down It’s a small location, with a cozy atmosphere. The curry ramen is rich and of a good portion size. The rest of the food here is also top notch. Staff is attentive and the wait for food to come out, wasn’t long.

Been coming here for years- super nice owners & great comfort food. We like miso ramen & black garlic oil ramen best but also have enjoyed curry dishes & appetizers

First time here and I went relatively cheap and simple with oyakodon. There was a good amount of red meat chicken for the price, lightly cooked and done shoyu/teriyaki style, only slightly sweet. Some fresh cilantro on top made for a nice contrast. Service was friendly and quick in this very small place, with jazzy music (including Sadé) playing quite softly. Service charge noted elsewhere is baloney, there is none. What is shown is only a suggested tip, otherwise the service charge would appear in the itemized total. My bill showed a range of percentage tip amounts at bottom. You do you. Pro tip for ramen: Don't drink the broth after finishing noodles, etc. Some is okay, but there's normally a fair amount of salt/sodium in it. It is permitted to leave the remaining broth. Small menu here, which I always feel is good in sticking to what works and always having fresh ingredients. I will be back for sure!

Who knew there was a great ramen spot near home. Excited to come back and try the other bowls. Great portions. Small restaurant, be prepared to wait if you show up anytime after they open. Definitely coming back.

One of my favorite ramen places around. Staff is always kind and service is great. Have not been disappointed in anything I have had on the menu. Highly recommended! Update from 2025: I'm glad this place has endured. Still one of our favorite date spots 6 years later. I miss the bar in the back where we used to always sit and watch them cook but I know in a post covid world its for their safety. Love the shoyu Ramen and their over rice bowls are still great and the pan fried gyoza still gives me nostalgia.

Best and most underrated ramen in the Bay! The broth is so flavorful, the texture of the noodles is perfect, and the pork belly is so crispy. Good portions for the price and the owners/service are great. My personal fav is the TanTan! Can be a little salty so request less salt :)
