I love going to T4. For a small place, they offer a wide variety of drinks and delicious comfort food to choose from. You order at the window, can either choose to eat at at their outdoor chairs and table, eat in your car, or simply take out. I love their takoyaki and basil popcorn chicken. Every time I introduce this place to friends, they're always amazed to discover how such a nondescript place actually offers a lot of tasty stuff. read more

Food: 0/10 Drinks: 7/10 Boba: 2/10 I really hate to do this to a T4 because generally speaking I think it's a great chain for Boba. They need to remove their food menu. We got their house chow mein waterlogged and very flavorless. Then we got The spicy wontons with some sort of mystery meat on the inside. We both spit up those because they were so disgusting huge waste of money. We were also informed that their food is very frozen when we asked for the orange chicken. Most of the food taste like it's been frozen. I'm the kind of person when I go to a restaurant I always eat my leftovers later. Nothing was worth keeping later cause it was all disgusting. We barely ate enough of the chow mein to make a satisfied because it was so gross. The female was snappy at everybody. The guy was fine. Their machine out front is horrible to use. It's frustrating and it keeps kicking you out of the item when you try to order.. It doesn't load fast enough so you can't see any of the images. It's absolutely terrible. Then to top it off when we tried to pay, it wouldn't let us it kept getting stuck over and over we had to actually ask them to ring us up through the register. Now for the Boba, we got the peppermint tea, which is fine and we got the taro milk tea, which is actually really really good. I would definitely come back for the drinks. Now the actual Boba itself is very hard and nasty clearly not freshly made. Keep that in mind when you order the Boba. read more

Love the thai tea and chicken wings. The wings are crisp and served with sweet and sour sauce.

Be careful when ordering from this restaurant. I found a staple in my Okinawa boba drink while I was drinking it, which was really alarming. Please double-check your drinks before consuming and stay safe. read more

T4 Vallejo - Okinawa boba with free staple. - Bubble Tea Near Me - Vallejo, California

Horrible service!! Took over 20 mins to make 3 drinks that weren't even great. Won't be back. Save yourself a trip. There's way better boba places then this place. read more

I don't know what's going on at this location, but taking 30 minutes to make three drinks is honestly unacceptable. I gave this place another chance after my first visit when they had just opened, thinking maybe it would be better by now but obviously not. We ordered before it even got busy, and somehow our drinks kept getting pushed back while other orders were made first. That's just poor organization. Saying there were only two people working doesn't really excuse it either. Plenty of boba shops run with only a little staff on the floor and still manage to get drinks out in a reasonable time. I've worked in that environment myself, so I know it's possible to make multiple drinks in less than 10 minutes.... like girl lock in are yall inspecting each tapioca in the back to ensure 1000% quality or what like bruh. read more

Even with all the warnings I still have to come get orders from here and when those orders are wrong no one gets yelled at but the delivery person. So once again, I am asking you to not go to this place. They refuse to do better. They refuse to pay attention to their customers. They refuse to even acknowledge their mistakes. This place should have been left alone or made into a Fosters Freeze. Or even a Dutch Bros. read more

T4 Vallejo - Please, pick another place. - Bubble Tea Near Me - Vallejo, California

My first visit here was good as I posted. My second visit did not go well. The young man taking my order refused to alter the heat level of what I wanted. Either our spice or the highway. I chose to change my order to sweet and sour pork. I wish I'd gone up the street to get a hot dog. While this order was for me, I took leftovers home. I offered to my wife, we agreed this did not taste good. I don't like posting bad reviews, I wanted this place to have good food after my first visit. This visit was a fail. I'm not certain I will go back and try something else. I did not appreciate the dismissal to change spicy ness of my order. read more

Ordering in this location is a headache. No shade when you order, order takes forever, they have a self service computer outside but not working properly, the person cannot take your order in the window because they have to finish preparing the orders of 4-6 people ahead. This is a weekday afternoon. Terrible speed, customer service. Once you get your order, take your food to go or eat in car only. Limited parking space. I do not recommend this place, there's a lot of options like Quickly, ShareTea, Devil n Angel. read more

Went here 11/22/2025. Got some chicken and some egg waffles. The egg waffles were burnt. I didn't know till I got home. Wasn't even edible. I more upset that they served this to us rather than make a quality product. The chicken was lacking in flavor. I know because we go there every week. Not anymore. This isn't the first time this has happened. read more

This T4 replaced the Dairy Queen that came before it. Came by during the soft opening and wow it was quite the surprise! This is the first t4 in an open area, so no sit downs but a spacious parking lot if you want to bring the stuff to eat/drink in the car! I have always been a T4 fan and this place didn't disappoint! I dropped by for some snacks, and they were prepped and served within 10 minutes, which as many might know is relatively fast for T4 standards. The staff were also super nice and accommodating. The basil popcorn chicken was OK, it's nice and crunchy while the meat is tender on the inside. The House mushroom was rather tasty too! I really loved the crunch it has to it, and it's nice have a meat substitute snack for those who can't eat meat. Overall the place seems nice, the only concern is that there isn't really space to drink/eat and the parking while closeby and convenient is somewhat limited. Hopefully they might be open to having a patio area out front, or arrange some seating :) read more

Love the milk tea, winter melon tea, jasmine milk tea! But customer service skills completely lacking. I came here and waited to order for about 5 minutes. There was a kid working but he didn't care to say "Be with you in a bit" or something of that liking until maybe about 5 minutes of me standing there. Then out of nowhere, another kid comes up to take my order. No smile, no hello, just waits for me to order. He clearly hated his job. I waited for my boba in my car and noticed the "Scan QR Code to Order" sign and broken kiosk outside. Just avoid the workers and scan the QR code and place your order. read more

I like the chow mein here! Also the mushroom appetizer has a good flavor. The fish filets are more fish than breading and not fried too hard. It's a drive up and grab kind of spot and the food is good. read more

Horrible service. We got told there was no boba but by the time I got my drink I saw the boba out. 2 drinks took 40 minutes to make.

Their tapioca balls the minis ones for the mango sago isn't made freshly it's hard texture. Those crab Rangoon tasted like it's been either refried or the oil needs to be changed read more

Glad they opened this place in Vallejo! My husband and I have been looking for new boba spots here in Vallejo - crossing my fingers one day they open up a happy lemon or something not too heavily focused on milk tea but more on fruit teas! We decided to check it out a few days after their grand opening and they were PACKED. I'm glad to know they took care of this place after the DQ closed, and T4 has a great variety of drinks as well as snacks - just be prepared to wait a little bit since the place is still fairly new and they are working out this new system! Besides that - I can't wait until the hype calms down and the wait time shortens a bit. The service when ordering was really fast, but it did take awhile for them to get my drinks and snacks to me! Parking is easy, as there is a small lot but it really seemed like a lot of people who live in the houses nearby simply just walk there! I can see it becoming a popular spot for students to grab snacks at the end of their school day too. read more

Their boba drinks are really good despite their prices going up. There's a kiosk to order items on. My favorite is wintermelon milk tea, nice and sweet. It's a nice little boba spot in Vallejo. My only conflict was ordering the fried oreos, it had popcorn chicken batter and seasoning on it with green onions haha. It was kinda gross on the fried oreos. Great boba drinks!

I just left this place and shout out to the male worker who I asked to make my popcorn chicken so spicy I regret it. He fulfilled my request and I'm in spicy heaven. No other popcorn chicken place has ever made it this spicy for me, I usually have to add extra or dip it in sriracha, but this was perfect just how it was. Thanks dude!! read more

this is probably the second time i've ordered a lychee black tea WITH aloe (as the name and title where i order it as) and i received it WITHOUT aloe. i don't understand how if it's in the name and on the tag where nothing says that i did not want the aloe how i ended up without it... i tried to call the store 6 times to let them know and got put straight to voicemail or got no answer 5 times. read more

Terrible customer service. I'm not sure if they were having a bad day or what but they had no customers there and the guy at the window was acting like I was bothering him by placing my order. The beef and broccoli had a terrible smell and the beef tasted like it was old. Popcorn chicken didn't taste so good either. I usually don't leave bad reviews but this experience left a bad taste in my mouth. read more

You should NOT go to this T4 for 3 reasons: 1. NOT EFFICIENT - Ordered 4 drinks which took 30 mins. Not terrible, but a lot of the drinks called out were out of order. Comparing the wait time to Sharetea, Tocotea, Boba guys (SF), and Urban rituals (SF) which ranges around 5-10 mins 4 drinks. T4 is the bottom of the list for efficiency 2. NOT WELCOMING - I don't expect to have top tier customer service at a boba place. However, considering they opened recently I expected to have a decent service. No smiles, no welcoming spirit, and not even a response to my thank you which I said to three employees. Felt like a number they just wanted to get rid of. 3. TERRIBLE QUALITY (MAIN CONCERN) - So my brother and I ordered two avocado smoothies. Immediately upon drinking I felt a crunchy and chunky consistency. - THIS WAS THE WORST AVOCADO SMOOTHIE I'VE EVER HAD - Didn't even bother blending it, had a sour taste, and I was too busy spitting out the avocado chunks even judge the taste. - It was so bad I put it through a sifter (The attached photo) to see how many chunks of avocado were in the drink. As you can see the drink was 90% avocado chunks. Didn't even bother blending it . Terrible quality avocado boba. Spare yourself from spending $20 and just go to another boba place. read more

T4 is a credible and well-known Asian bubble tea franchise authentically hailing from Taiwan. Menu offers a wide range of drinks and snacks. Operations was smooth for a new location. 15 min wait time for 2 orders with no line around 3pm on a weekend. Staff were quick moving and professional. Go to the front window to order. Side window is to pickup drinks. There is no signage to help orient you, so don't huddle by the crowd typically waiting for drinks. This is a walk-up counter location with a small designated parking area. No seating (not an ideal hangout spot anyway - read below). FYI, this T4 location is a standalone building that's pretty exposed to the roadway. This naturally means more street noise and traffic air pollution. This would be a quick grab-your-drink-and-deuces kinda spot. We ordered the jasmine green milk tea with boba (my standard benchmark for gauging the quality of boba stores), 80% sugar, 50% less ice. Tea was decent, boba had a good soft texture, but sweetness level was made too low (tasted like 50%). You can always ask them to adjust your drink but I wasn't gonna be overly harsh on the sugar level miss. All in all, I'm glad to see another Asian owned business in V-town and will be glad to support them. Gotta give props to good food, good drinks, and making our community more culturally diverse. read more

So I gave it another chance since they added all these new items. Hoping to have some simple Chinese food sound simple enough. Except the fact that when I order 6 items and 3 items are community what order. When trying to ask them what they gave me they couldn't even answer. I showed them my receipt and the pictures they had on there menu. Which was completely different. It got to the point of what's the use of arguing as it's gets no where. I complain and ask them to fix it. They changed one of the item. Refuse to fix the other. I spent almost $100 on 6 item. But the worst part was when we got it home. The meat were bad it tasted spoiled. We tried calling no one answer the phone...when I got home it's was almost 7:45 and they closed at 8 so what's the use. Lesson learn tried this placed twice both in disappointment. I won't be back for a 3rd time. I would love to support local business but at this point there's just no point. Good luck. Staff all seem lost or don't know how to handle complaints. There are no dine in which is plus for them since that way you can't bring back to complain. read more

I thought this was gonna be my new boba spot but honestly I am DISAPPOINTED BIG TIME. This is about their snacks, maybe today was an off day but aint no way they charging $9.25 for fried calamari and I literally get half of a half order, mind you it was overcooked. I literally just opened the box for it to be this much in there? Please get a manager or someone EXPERIENCED to run this place. It could be great but they have literal children running it so it's not gonna be good. Ill still go here for drinks prob but f these portions for those prices! read more

Food too good, I had to stop to take a picture before I totally demolish these noodles and shrimp. I haven't eaten all day, so this photo is a must last time I ordered the Singapore Noodles with Shrimp, and will be returning again!! The server was super nice, and pleasant! Ordering then picking up works best for me, just because there is no area for dining. Hands down, best chow mein noddles so far that's I've had.

Food and drinks are great and always consistent. My son loves their popcorn chicken. The staff was friendly.

This place is a joke. Rude and unprofessional staff make the experience not worth it. Every time I've came here, staff have talked down to me and told me to "be careful next time" when the machine had messed up the order . Plus they always forget 1-2 toppings I've ordered through the kiosk. You're better off getting boba anywhere else in Vallejo. read more

We decided to try this new place T4 (former location of Dairy Queen) on Springs Rd., Vallejo, CA. The food we ordered was based on the pictures we saw on Yelp photos. We had fried mushrooms, fried calamari, salt and pepper fish and to drink, mango tea. Hubby and I really liked the flavor of the food except they were too generous on salt! Next time we will ask them to be easy on the salt! But they were perfect on crispy and crunchy! The service was good and quick with people already lining up to order. It's a small place so taking food to go is best! We will definitely try other items in the menu! Hope you all try this new place! Have a blessed day! read more

I've been here twice so far. The first time, I ordered 4 drinks for my family and me. I only tried my drink, the Apple Black Tea with boba. I also ordered for us their House Fries, House Mushroom, Popcorn Chicken, and Calamari. My drink was so good... so refreshing. It had a few real apple bits and I finished it in like 10 minutes even though I had a large. LOL. The boba was soft and chewy too. The second time I came I also ordered the same drink and fries again. And the food, I will give 4 stars to everything. It was all seasoned so well with seaweed bits and other spices I don't know. My favorite was the House Mushroom. My mouth is watering as I type this. I'm not giving 5 stars only because I don't think it's possible to change the spice level on the food (not that it's legitimately spicy, but the option is still nice). The cashier I had the first time was super friendly and welcoming. She was pretty funny too. The second time the cashier was also patient and nice. I also talked to one of the other employees, he might've been a manager or supervisor, and he was also pretty bright and helpful. But, like I said before, I've been here twice. And both times the drinks came out reasonably fast but the food took 30+ minutes. I've only ever went when I had nothing else to do so I didn't mind as much. Especially since I could tell from looking into the windows that their setup is cramped and crowded. I used to work at a bar and just looking inside their workspace I was feeling overwhelmed lol. I don't know how they do it. I also overheard one of the managers(?) explain that their fryer "can't handle it" when asked why the food took so long. Not quite sure what that means, I don't fry food so! One suggestion I have would be for the cashiers to give a heads up whenever someone tries to order food and tell them that it would take about 30+ minutes if there's a lot of food orders and the fryer can't "handle" all of them. That way, the customer can decide if they have the time to wait or not. (Both times I've went, I've heard people around me grumble about the wait times, which is valid I suppose if they weren't aware of how long it'd take). Also, there's no tables or chairs outside so you'd have to either eat and drink in your car or go somewhere else. The city I grew up in had like 7 boba places within walking distance of my old high school so I take my boba drinks very seriously! (Jk, kind of.) This boba spot is definitely the best one, drinks and food wise, in the area. Once they get their food and drink serving time on lock, I can change it to a 5 star review . read more
