    The roasted oolong milk tea is delicious and I added watermelon seeds! It's not too sweet so it's perfect! The Thai tea was good but the tea isn't too strong of taste. The service is pretty quick since there's a self serve kiosk.

    Great location in downtown Hayward and open late, which is always a plus. The staff was friendly and super helpful, and the place was clean inside. They even have games you can play while you're there, which is a fun touch. I ordered the chocolate milkshake with 50% sweetness and almond milk--so good. Highly recommend!

    Quickly / T4 not sure of the branding. Either way they make a delicious Brown Sugar Boba Milk Tea, added Oreo for personal preference

    Rose milk tea

    I can't find rose milk tea in other places so I was over the moon when I saw that there was a T4 while I was walking. There was one in Castro Valley that closed a while ago. Since then I moved and I always kept my eye on finding rose milk tea but didn't have much luck. It was good I'm no expert on bobba tea but I found the flavor that I was looking for so that's great! I got 50% sweetness and it was perfect sweetness for me, not too sweet.

    Popcorn Chicken nice and crispy

    Ordered on DoorDash for me and some coworkers. Loved my drink order Taro Milk Tea w/ sea salt cream. My coworkers were happy with their drink orders as well. Popcorn chicken is good, I asked for a side of chili powder which wasn't given. I know when you go in person you put your own chili powder, but they should have a better system for people who order on DoorDash.

    Service was amazing and they were so patient with me! Nice and spacious and it smelled amazing. I tried a new tea and the popcorn chicken! So glad I found a place that I can relax in. I'll definitely be back!

    Inside

    I decided to stop by to get a hot drink since it was cold outside. I didn't have to wait long after I placed my order since there were only a few people inside. My go-to order is The Earl Grey Milk Tea with Agar Pearl 50% sweet. The agar was super melted when the drink was hot, but once the drink started to cool down, the pearl was the perfect texture (super chewy). I have ordered this drink in the past, and from my memory, it was always chewy even when the drink was hot. Guess this means I will have to come back again to give this drink a try and do 0% sweet.

    Popcorn Chicken

    I stopped here on my way to the movies next door and it did not disappoint! I ordered popcorn chicken and it was cooked perfectly plus they had Sriracha sauce! The caramel milk tea tastes authentic and not powdery. It is also very spacious with 9 tables inside and restrooms available for customers. The employees are very kind and provide quick service. I'll definitely come back next time I'm in the area!

    Strawberry lemonade & Oreo
    Javier P.

    It's been a few years since I've had T4. Not into it like I used to be. Walked in with my six year old niece because she was thirsty and wanted the Oreo drink and the strawberry lemonade for me. I returned 30 minutes later with my mom, my sister, and my seven month old niece past out in my arms because they were getting their nails done earlier. My niece started making moves on the new drinks lol. It wasn't busy Sunday afternoon which made the service fast.

    Ordered fried lobster ball, egg puff, popcorn chicken, takoyaki, fried squid, and taro milktea with honeydew popping boba for delivery. Decent snacks and drinks, nothing to rave about. Popcorn chicken didn't come with spicy powder. Tip: heat the egg puffs in the toaster oven to make them crispy.

    My favorite popcorn chicken
    Lai L.

    T4 has always been one of my favorite boba places to go. We usually always order the same thing each time we go because we know what we like. I usually like to call in before I go, because their online ordering system is a little slow. I think ordering via phone or in person is faster. The staff is pretty friendly and their drinks always hit the spot. I always have to get the basil popcorn chicken when I go. They have the best popcorn chicken! I don't know what they put in there, but I know there are a lot of spices! My go-to milk tea is always the wintermelon, and my husband and son always get their favorites: pineapple slush and strawberry milkshake -- all with boba! I like that all the T4 drinks are consistent every location I go to! I also think the location is great...a little of a drive for me, but worth it.

    Love the service when we go here. Staff is always friendly and service is fast. Place is always clean and organized. Nice location in downtown near other establishments in case you want to hit other stores. Limited strew parking but there is a free parking by the movie theater, walking distance from the location.

    If you enjoy cute character desserts, delicious drinks, and an overall cozy cafe experience, I…read morehighly recommend that you stop by Always Yours Bakery Cafe! Not only are you able to purchase from their bakery case, you can also request to have desserts made for special events! (In advance of course.) I very much enjoy their macarons and fresh fruit tarts. They also added Banana Matcha to their menu when it became a craze, and I 10/10 would recommend it. They use high quality matcha powder (Marukyu Koyamaen) for their drinks. This is one of the few things that drew me into their cafe. The baristas are extremely friendly and have a wonderful sense of humor, AND they support small businesses! While you wait for your order, you can browse their shelf full of crystal candies, matcha sets, candles, and they may also have Natsume matcha tins available! (This is not the matcha they use in their drinks, but it's nice to have other options available to buy.) ^^ So if you're in the East Bay and are looking for a business to support, go to Always Yours Bakery Cafe (they're also available on the Too Good To Go app)! They have beautiful outdoor seating available, as well as cutesy seating indoors. Not sponsored or anything, I just wanted to review one of my favourite cafes in Castro Valley. ^^

    Over the years, I've been a loyal supporter of Always Yours, dating back to the early days. When…read moreNatalie opened up right here in Castro Valley, I was ecstatic to finally have a high-end macaron and drink spot in town. For the first few months, it completely lived up to the hype. The character macarons were incredibly intricate, and the drinks easily rivaled the top-tier boba shops in the area. However, as the shop has scaled and commercialized, there has been a noticeable shift in consistency. With quicker turnarounds and the typical high turnover of part-time staff, the execution just hasn't been the same. While Natalie has mentioned investing heavily in upgraded ingredients behind the scenes like scratch-made syrups and ceremonial grade matcha, those drinks often lack consistency in sweetness, in toppings, or overall execution. The macaron flavors feel much more muted than they used to be, and the character designs look a bit more rushed compared to the incredible creativity of the early days. I have immense respect for the incredible amount of solo grind and dedication it takes to run a local business for five years, which is why I've supported them for so long. But as a longtime fan, it's just disappointing to see the final execution drift from the incredible standard they originally set. I genuinely hope the team can find their rhythm again and bring back those nostalgic memories.

Parking is a little weird and very limited but luckily for us, we found a spot on the side of the building. There were two young ladies working the store and the menu is basically posted everywhere. My daughter and I immediately gravitated to the banana matcha latte. We also saw they had yummy croissant pastries available, so we decided to give that a try. What we got: 1. 2 banana matcha lattes- 4/10 the matcha was okay but we tasted no banana to it besides the slices of banana. The pudding tasted like regular vanilla. Overall just not what we were anticipating. 2. Brown sugar boba milk? - 0/10 This was just milk with a bit of brown sugar syrup. (See pic) I actually dropped this off to my other daughter and she said she just couldn't drink it. 3. Strawberry croissant- 8/10 This was actually good. The strawberries with the jam and whipped cream were very good. Don't get me wrong, service was fine. They also had a few great items but the actual drinks were mid. I think the matcha needs to change or maybe making it more paste like could help boost the flavor. The brown sugar latte was just not it.

They made my day better after interacting with her. I ordered a drink for my wife and she decided i didn't order it correctly so I asked if they can change the order.

The drinks are also excellent and I really liked the taro drink with fresh taro. It'll be nice with even a little more taro or taro paste.

Everything is sweetened at 50% so you can gauge what you may like in your own drink. I've been coming to this teaspoon since they took over the Quickly that occupied this space. Let me say this was one of the best things to happen to this area. This particular teaspoon sets the standard high on efficiency and quality of their products. I can't remember ever saying my drink tasted wrong or took too long to make. The workers are always on top of their game. You can also save some time and order online through doordash. They're usually very quick with online orders. We usually get either the lychee on lychee, peach oolong or the guava sunset. As mentioned, their drinks lean on the sweeter side even at 50% so if you want something more light definitely opt for 25% sweetness and less ice. For fruitier drinks I usually opt for crystal boba but honey boba works too if you want a chewier texture. Overall can't wait to be back and highly recommend.
