This has been our goto Taiwanese takeout for years, but the food has changed last month when we ordered. Fried taro ball filling wasn’t filled with taro, but a starchy version of it. Fried chicken in the bento had way too much flour covered that it dried out and became hard. We threw away much of it. Please don’t sacrifice quality. We’d rather pay more than having substandard food. Will not come back unless improved.

“I ordered a chicken bento box tonight with a side of broccoli and clear noodles with the drink of Lychee Black Tea.
Shortly after I got home, I became very sick and have been vomiting everything I ate tonight. Extremely disappointing experience. There must have been something wrong with the food tonight.

To respond the owner 9/24 I was in your restaurant on 9/21 around 7:13 pm. The picture showed exactly what I ordered. I vomited everything I ate that night and then was I was fine with all other food the second day. If nothing is wrong with the your food, what else could be wrong?

As a delivery driver I kindly asked about restroom for 2 minutes. One of their employees (young girl) answered rudely. Hey Chinese people, you are not in China. This is America (USA). It is appreciated to be respectful

deliciously authentic taiwanese food in american portions. i was able to split my 排骨便當 into two separate meals. still tasted great as leftovers! very impressed with how well the 滷 process was carried out with the 排骨. the curry on the side was also a highlight. japanese style curry — just how us taiwanese people like it.

Love this place! It was my gateway to Taiwanese food. Both food and value is amazing for what you get. I always order takeout or delivery, and they never fail to pack the boxes to the brim. I get food here 3x / month, at least, and quality and service is consistently good.

In your bento box, there are always two rotating side dishes with your main entree, as well as the staple rice with minced pork and a marinated boiled egg. The portions are great and tastes like a homemade meal.

Sometimes I make a special request to have no rice and add more vegetables instead, and they are super friendly and accommodating about it.

Parking lot can get quite packed because it is in a lot with other busy restaurants.

Their milk tea is super strong. If you get one too late during the day, prepare not to fall asleep at night. But the taste, one of the best in the bay area. The boba chewiness is so so. So I don’t usually get boba with my milk tea. We also love their basil fried chicken. Their mushroom spicy sauce is yummy too.

We got the food from company group order. The package is nice! Small three side dishes and one entree. The tomatoes eggs are pretty sweet. The eels are very soft and heavily marinated.

Really enjoyed this place! No mandatory tipping, which made things feel more relaxed. The self-serve setup for utensils and sauces made everything super convenient. Food came out quickly, and the flavors are very well-suited for Asian tastes—familiar and delicious. I’d definitely recommend it to anyone who enjoys fast, flavorful meals with no fuss.

I don't recommend any service fees at all, as you have to clean up your table. The shorty cashier (maybe called Daphne) is extremely rude, gave us the cold face. Also food is loaded with MSG which made me sick at night. Avoid this place

The popcorn chicken is so good. Takes me back to Taiwan!

Classic boba milk tea had more tea flavor than I expected. I did 50% sugar but I would increase to 75% for more flavor next time.
