Reviews
Before visiting this location, I highly recommend being weary of the influx of positive feedback you see online. It appears they frequently promote freebies or rewards for 5-star reviews, which creates a very skewed and dishonest representation of the actual customer experience. In reality, the operation is plagued by rigid policies and a lack of basic customer service. One of the most frustrating aspects of this spot is that, as usual, there is no customization of the drinks allowed. In a market where almost every other drink shop allows you to adjust ice or sweetness, their refusal to cater to guest preferences feels outdated and lazy.
Declining Service and Difficulty with Exchanges
I have visited this chain before, but the Redwood City branch seems to be struggling with basic hospitality.
Unhelpful Staff: On previous occasions at other locations, I’ve been able to exchange a drink if it was made poorly or tasted off. However, this time the process was much more difficult to get done.
Lack of Accountability: The staff was dismissive when I brought up the issues with the order, making me feel like a burden for simply wanting a drink that was drinkable.
Consistency Issues: For a place that prides itself on “handcrafted” items, the lack of flexibility and the downward trend in service quality are major red flags.
⚠️ Serious Health Concerns and Quality Control
The biggest issue with this visit was the physical reaction to the product.
Terrible Quality: One of the drinks we ordered was absolutely terrible. It didn’t just taste bad; it was clearly prepared incorrectly or with ingredients that had turned.
Physical Illness: Shortly after trying the drink, it caused abdominal pain that lasted for quite a while. When a dessert shop’s products lead to physical discomfort, there is a fundamental failure in their kitchen’s health and safety standards.
Safety First: I cannot in good conscience recommend a place where the quality control is so low that the food becomes a health hazard.
Final Thoughts and Recap
To recap, this was a completely failed experience. Between the artificial 5-star reviews, the total lack of drink customization, and the difficult service when trying to rectify a mistake, there is very little reason to visit. The fact that a drink caused abdominal pain is the final straw for me. I’ve given this place enough chances, but I won’t be going back to this one. There are far better, safer, and more accommodating dessert spots in Redwood City that don’t rely on “rewards” to maintain their reputation.
I ordered the Tropical Mango Matcha with crystal boba, less sweet, less ice, vegan matcha, and house coconut milk — and it was absolutely delicious!
The layered colors are beautiful — the deep green matcha, creamy white coconut milk, and bright yellow mango — and the texture is smooth and refreshing with a touch of real mango.
The flavor is perfectly balanced, not too sweet, and the matcha aroma stands out without being bitter. The clear crystal boba gives it a light, fun twist compared to regular tapioca.
The shop itself is super cute — clean, nicely decorated, and calm, perfect for sitting down and enjoying your drink.
In addition, this place’s ambiance is mellow with great customer service. Friendly staff and one of the nicest tong sui I’ve been to. Would definitely come back.
Some of my favorites:
Matcha Cold Brew
Coconut Breeze
Coconut Rose Latte
Mango Mochi Pudding
Mango Sticky Rice Pudding
They can get busy during rush hours but have order ahead. And…cashless.
