Popped in today with more friends for fried calamari appetizer (light and yummy), pineapple chicken curry rice (ridiculously good), sex on the moon roll (yes please) and three's company roll. YUMMY goodness! The sushi is so fresh that it melts in your mouth.

Tried Thai Thani and loved it! The food was fresh, flavorful, and beautifully presented. The crispy appetizers were perfect with the sweet chili sauce, and the grilled beef dish was packed with delicious Thai spices and came with a bold dipping sauce that really hit the spot. Great flavors and friendly service — definitely coming back!

It's two restaurants in one! You can have Sushi and Thai food all together. Have satay and a sushi roll 😋 with a Thai ice tea! Service is quick and friendly atmosphere is relaxing. They have some outdoor seating, too.

We enjoyed another great meal at Thai Thani. This time we ordered a variety of Thai and Sushi. The rolls were delicious! I love when I don’t have to ask for fresh ginger and wasabi. […] The staff are all warm and friendly and you will be very happy to try this lovely restaurant. We will be back!

The customer service is really cool. The restaurant inside itself was really nice. I got the three roll Combination lunch special, which would be beyond filling. It was all very good, very fresh,…

Excellent Thai and Japanese cuisine, warm and friendly hospitality, authentic theme throughout the restaurant will make your evening complete. […] Would highly recommend my favorite Tom Ka (Thai coconut soup) and Sushi Sashimi plate to have a taste of all of it.

Thai Thani (Thai restaurant) and Oishi (Japanese Restaurant) share a very large space. […] My Phad Penang chicken dish had a nice spice to it which I really liked.

Very positive experience. Chatted with Yoshi, the head man behind the bar, about the restaurant, the fish suppliers, soft opening vs grand opening, etc. They're definitely in the "getting the kinks worked out" phase and everyone is committed to finely tuning the experience so that by grand opening day it's a purring machine.

Visit

One address, two phone lines.

Thai Thani invites you to “experience the bold flavors of Thailand while dining in our warm and relaxing environment.” Oishi calls itself “your one-stop Japanese steakhouse restaurant,” with a fully stocked bar.

Both restaurants opened together at The Orchards shopping center on Ygnacio Valley Road in 2019. They share one large dining room, and guests often order Thai and sushi at the same table. The decorative artwork in the restaurant can also be purchased; ask your server for details.
