This is a cute boba shop I just discovered! Highlights of the menu: 1. Avocado zen 2. Kuro milk cheese tea with mixed boba (large & small) 3. Aichi green tea crumble 4. Ceylon milk cheese tea with grass jelly Automated ordering system is saving so much time! So in love with the drinks here! Love Yakul in the drinks, very fresh and yumm. It's so cool to have boba next to the samurai. This place is so fun. Who doesn't love Orea crumbs in the drinks. I can never buy 1 boba here, need to stock up the fridge! And they have free stickers for customers. Lovely! read more

Mango Zen: Really delicious! I didn't really understand what the zen cream was but it was very thick and added lots of flavor. The boba itself was really good! I enjoyed Inside: No inside seating, I came when they were doing an event. Looked very clean and the decoration was interesting! Self ordering kiosk and didn't really interact with any workers. Outside: No outside seating, found in a plaza so plenty of parking! Overall pretty good if you're in the area :) This drink was really good! read more

It has been two months that I revisited and many things has changed, in a good way. They put couple tables with chairs, start serving Bungeo-ppang and the Samurais moved behind the Kiosks. The big LED screen wasn't operating so I thought that was a bummer since it was such an awesome display. On the other hand, the service and the quality of the drinks remained the same, which is most important. I just love the large selections of their drinks. That is what makes this place so unique compare to many other boba drink shops. Always a pleasure stopping by and enjoying their sweet treat! read more

This is a quick one. Nice samurai theme inside. As far as service, I was dumb and didn't know everything was self service on the iPads out front. So I stood there for a bit looking at the staff thinking they were ignoring me. Don't do what I did. I got the strawberry Yakult with boba. Very creamy tart drink and I drank it within 20 minutes... which is good considering I had a full belly. Every sip painfully expanded my stomach but I could not resist. The boba pearls could be selected large, small or assorted. I got assorted. They were hard but for some reason I enjoyed the difference in textures. If I'm ever in the area I'll drop by. read more

The variety of drinks they have here is crazy and almost overwhelming because they all sound so good and it's tempting me to try out the entire menu. For that reason, I tried to get a drink from every category so I could sample a little bit of everything. Avocado Zen: They put a whole avocado in here! This made the drink super creamy and I asked for it to be 25% sweet so most of the sweetness came from the strawberry puree which I didn't know worked as such a good combo with avocado. House Taro: When a boba shop uses real taro paste and not powder, you know it's the real deal. Mix the taro and milk together to get the perfect creamy, nutty sip. Aichi Milk Tea: I love the quality of the matcha they use. I'm not sure if it was ceremonial but the powder itself was very vibrant and strong. I find it hard to find good matcha drinks but they're not lying when they call it premium. Cookie Creme Sugar: I got this for my brother and didn't get to try a sip but he really liked it. I'll just say that this is for all the sugar lovers out there who have a big sweet tooth. The quality and variety of the drinks here make it worth visiting again and again until you can confidently say you found your favorite drink. The workers were also kind but you don't necessarily have to interact with them because there were multiple kiosks to order from. There's also a small bench inside but it's more of a grab-and-go type of place. read more

Cute little boba shop with a variety of flavors to choose from! The drinks are customizable in terms of sweetness and any other add-ons you may want. I got the Aichi Green Tea Crumble and Cookie Crème Sugar. They are not stingy with the cookie portions on both drinks! I will definitely come back to try their other drinks! read more

Jasmine milk tea was very fresh and aromatic. Definitely worth a try. I think it was too strong for me and could use more milk though. They had a kiosk so you can order through a tablet. I got my drink within 5 minutes. Very quick service. read more

Stop reading reviews and GO GET A YAKULT DRINK ASAP!!! Katsubo perfected a Yakult drink with the perfect amount of all their ingredients! What's most impressive is how fresh and real their fruit incorporation tastes; not syrup-like or artificial! They really hit it out of the park with their creative Yakult drinks. Unfortunately, I can't speak upon the rest of their drinks, for the reason that I can't go and not order this Strawberry Yakult drink! But I'm certain they're amazing, too. read more

Best matcha in OC. Ronin Matcha offers an exquisite matcha experience with the finest sourced from Japan. This is their signature frappe with house-made sweet crème brulee pudding, served alongside strawberry puree. Mango Zen is also a delicious specialty drink. It is a refreshing mango smoothie served with unique house cheese foam and fresh mango bits. I recommend trying Ronin Matcha--it's a must-get! I had a great experience with Katsubō Tea. Can't wait to try other drinks. read more

Stopped by on a Saturday and was in and out quickly. I ordered via the kiosk but employees were available to answer some questions. I selected two drinks, the Jasmine Milk Tea with added crystal boba and the House Taro with added Katsubo Boba. The Jasmine tea was extremely fragrant. Crystal boba is good quality and nice balance of chewy and firm. Adjusted to less ice (no ice not possible) and 25% sweetness, which was appropriate with the Crystal boba. House Taro uses real taro, non-caffeinated and good for kids. Katsubo boba is a blend of large and small brown sugar boba, different texture but I slightly prefer just large boba (small ones would stick to large ones and were slightly messy). read more

Katsubo has a large selection of drinks to choose from. It's located in a large plaza so parking wasn't difficult. I tried the Katsubo Brown Sugar Boba Milk Tea and the Aichi Green Tea Crumble. Both drinks including their boba was good. The Aichi Green Tea was a little icier than I imagined, but they do use good quality matcha powder. They use self-serving kiosk stations and there's no tables to hang out, but there's a bench to sit and wait for your drinks. The worker was also nice and even provided other recommendations in the plaza. read more

I like the self serving kiosks! I still don't understand why a tip option even comes up kinda weird you're pretty much doing everything by yourself except for pouring the drink into the cup! The girl at the front barely acknowledged my presence ! She hardly wanted to help me figure out how to check out on the kiosk. The drink was mediocre nothing too crazy either. I would be back for the convenience & price read more

Best boba in town. My son and I frequent this establishment and the boba is fire! The service is fire! And the place is really cool as well. Pet friendly as well as we take our husky/malamute and he also gets a small snack as well. Thank you! read more

Really love the tea options here! The service was so quick, I didn't even notice that they finished I also loved that I could easily order on the computer. The Taiyaki was only an extra dollar. I thought that the price was good for the quality. But I wouldn't be excited to order it again. The four seasons tea was great for something refreshing but I regret not getting something milky. The place is great for big groups getting boba, you can't really sit down for a long talk. It's more about going in for a quick drink. read more

My friends and I were craving milk tea and none of us had tried Katsubo, so we decided to make the drive. I got the dark roast oolong milk tea (with their house milk), 25% sweet with less ice. I love oolong milk tea, so I was super pumped to try a new company's oolong tea. Honestly, I didn't love it - it tasted more like black tea. My friend also got the same dark roast oolong and we agreed that it didn't taste like oolong. Maybe it's just the dark roast that's throwing me off, but I didn't enjoy it as much as I hoped. In terms of service, I ordered through the self-serve kiosk. I like the idea of a self-serve kiosk since some customers order tons of drinks with adjustments. It's also nice to see how much each adjustment costs (for example, cheese cream) before you place the order. There weren't any customers when I walked in, so my drink was ready within 5 minutes. If I come here again, I would want to try a different tea that's not oolong. read more

Came here after walking around the area and was pleasantly surprised. Upon walking in, it felt like we had just walked into a sci-fi movie. There was a life size samurai statue and a whole wall covered in screens showing the menu and the drinks. I came with a group of people and I decided on getting just the Kuro Milk Tea. The drinks came out fast and were all very tasty. read more

This place is good with their specialty boba drinks. I got the strawberry matcha 75% sweet and wow the matcha is really quite strong, they didn't skimp on the flavor.

Came here in the afternoon after lunch on a weekend. It wasn't too crowded. Located in the same plaza as a grocery store, so there's plenty of parking. The inside is pretty cool and one of the walls is a huge screen that displays the menu and other cool graphics. If you have a hard time reading the menu on the large screen, you can just look at the menu when you're ordering at the kiosk. I didn't want to get anything too sweet after lunch, so I got a fruit tea. 50% sweetness here is actually 50% sweetness, which was surprising to me since 50% is usually still pretty sweet at all the other boba spots. They have a lot of toppings - I like that you can get a mix of regular and mini boba. The drink itself didn't really stand out to me, but it was good. Happy with what we ordered, but definitely gotta come back to try their more popular drinks. read more

We wanted to try out this spot because their beverages looked like OMOMO's with the frosted cups. Katsubo is located in the plaza off Malvern so there's plenty of parking. They have various specialty drinks, so we ordered the: *strawberry zen (strawberry smoothie with cheese foam) *thai creme: tasted like a thai tea, but slightly watered down/not as concentrated *strawberry yakult: this literally tasted like a strawberry yoplait yogurt (interpret that as good or bad as you will) Overall, I think the quality of the drinks are comparable to other boba shops in the area. I wasn't a huge fan, but I think it's a solid option for boba if you're in the area. read more

Based on the reviews and photos, I was really looking forward to getting a nice strawberry matcha on a rainy day. Felt very cold and impersonal going into the store. Completely empty, and the gal up front on her phone not getting up from her stool, with no greeting. I order and pay at the kiosk with zero interaction. Drink comes and I initially I think it's incorrect because I don't see the red in my drink. But I look closely and sure enough there is some slight pinkish discoloration, and that is the extent of the strawberry in my strawberry matcha :( read more

I was in a search for a non-caffeinated fruit tea boba drink & was pleased to find that they have here the Berry Berry Lemonade. I ordered it with 25% sweet with boba & it was made just right! The drink was refreshing with the strawbery tea flavor mixed in with lemonade, it was not sweet as requested & the berry bits were a good add ins for texture. The boba was decent quality as well. I've ordered their brown sugar milk tea before too when they first opened, I remember it being good but have yet to order it from here again to refresh my memory, but the berry berry lemonade I definitely recommend! Service was also quick, and electronic kiosk was available for easy ordering. read more

A TWST cupsleeve event was hosted at this location, and the staff were nothing but accommodating! We were immediately greeted by staff when walking in and the shop even changed their digital screen to showcase details of the cupsleeve event. They had a decent amount of chairs to sit around but I do wish they had tables. Anyhow my friend and I got the Strawberry Zen and Aichi Milk Tea. My friend enjoyed the Aichi Milk Tea sightly more than the last time she came here. She had caution me that the drinks here are so sweet, so I made sure to adjust my Strawberry Zen to 50% sweet. Even with the adjustments, it was still pretty much sweeter than what I'm used to at other boba shop. I recommend making the sweet 25% or even 0% since strawberry itself is sweet. Overall the staff here are super nice and accommodating! The shop has AC, and chairs to sit around to chat. They are located in a plaza so parking is easy here. read more

Katsubo Tea is hands down one of my favorite boba spots. The drinks are consistently fresh, flavorful, and customizable, which makes each visit feel personalized. They have a wide range of options--from creamy milk teas to refreshing fruit teas--and the toppings are always on point. The boba pearls are soft, chewy, and never mushy or hard (huge win!). I especially recommend the Tiger Sugar Milk Tea or the Lychee Green Tea with Aloe. Both are perfectly balanced in sweetness and really showcase the quality of their ingredients. You can adjust sweetness and ice levels too, which I appreciate since not everyone wants their drink super sweet. The service is fast and friendly, and the staff genuinely seem to care about making sure your drink is just how you like it. The stores are usually clean, modern, and welcoming--a great place to chill with friends or grab something on the go. Pricing is pretty standard for boba, and honestly worth every penny for the quality you're getting. read more

We love the boba and quality of milk that is used. Honestly, one of the best boba places in Fullerton!

Mainly came here because it's close and open. Seems like a revamp of the place happened since it used to be less welcoming before (closed off space and little seating, etc.) The drink was okay?

I'd definitely come back to this spot and recommend to those around me! read more

First timer at Katsubo Tea! Ordered the dark roast oolong milk tea 25% sweet with small boba for me & the katsubo sugar 75% sweet with large boba for my fiancé! I love a milk tea that is tea strong & not too milky! The 25% sweetness level was perfect for my liking! It's very rare to find a boba spot that sells small boba! This is what definitely caught my eye and made me want to try it. I'm so glad I did because their small boba was a great chewy consistency and was not over cooked like other boba places! I believe it was the shop owner who approached my friends and I. He was super friendly and asked us if we needed help with choosing a drink. He gave us free stickers too! Super cool! The service was great! The ambiance is super cute with a bench and some lit squares to sit on! They have a cool screen that was projecting Kpop as well! I'd recommend visiting and trying their drinks out! read more

The first time I came here, I didn't really like it-- I felt like the quality was off and the prices were a bit too extreme. However, I decided to come back and try again a few weeks ago! It really changed my mind. I got the white peach oolong tea and it was really good. It was not too sweet even though i did 100% sweetness and I also got lychee jelly in it. My brother got the house taro and it was kinda weird to see the color of the drink. It was a light brown-ish color instead of the classic purple that we see in other stores. The boba quality is pretty good here! I don't remember what I didn't like exactly from the first time I came here but now I come here when I need a boba drink fix. The place itself is pretty small. There aren't a lot of seating options. It's more of a to-go store. There are two self-serve kiosks and the employees are usually behind in the kitchen making the drinks. The drinks come out pretty fast though so no complain there! There are a lot of random decorations everytime I come but I usually don't mind it. When the TV is on, it does get a bit funky but it's usually not bothersome either. Overall, I definitely will be back! I love the fruit teas here and my brother loves the taro here, especially with crystal boba. I would recommend it for sure! read more

As someone who's incredibly picky when it comes to boba, I've been on the hunt for the perfect place for a while. Katsubo has officially become my favorite spot in Fullerton! I tried the ube milk tea with oat milk, requesting the lowest sugar level, and it was perfection. The drink had this amazing sweet flavor, but it wasn't overpowering or sugary--just perfectly balanced. The boba was spot on--chewy and delicious, and the entire drink was refreshing. If you're a fellow boba lover with high standards, I highly recommend giving this place a try! read more

Love this boba place! My husband randomly found this place and went in and I'm sure glad he did. I love their grapefruit slush drink. I've tried their other drinks too and they're all good! The only minus is that the staff is always talking to each other behind the wall that it's hard to get their attention. Oh! There's no tables for people to sit and chat at. They have random K-POP events there. So it does get a bit loud on those days. read more
