    had come here during an "off" hour so it wasn't too crowded. service was quick and simple - ordered boba milk tea with spicy popcorn chicken and it was the same as anywhere else - glad they're consistent. little indoor seating but i'd prefer to grab my drink and walk around downtown.

    I lovvvve happy lemon I think it's the best boba on castro street! They do get crowded but there is a lot of seating. The egg waffles take a while but they're sooo good, last I checked they also give a generous amount of puff cream or salted cheese with the waffle. My faves drinks: Go to order: Salted cheese milk tea 50-75% sweet Other good orders: Matcha latte with tirimisu foam 50% sweet Matcha Mango smoothie Mango Milk tea with Orange and lychee jelly 50% sweet (this is really good) I had the genshin teapuccino recently. Would not reccomend - it's like a worse version of their regular milk tea but more watered down. Also if you're a regular here I reccomend getting the app!

    popcorn chicken

    I ordered the popcorn chicken and it's $10 for a half full box? Absolutely ridiculous.

    I like happy lemon. Always same and good quality in this location. Just one thing is; they are very slow. But this is common at Tea Shops hahaha I don't know why :)

    One of my favorite boba spots! Consistently great drinks and quick service across their many locations. Some of my favorites are: - Strawberry green tea - Mango matcha smoothie - Matcha latte w salted cheese (and their salted cheese drinks in general) - Over the summer I've had a berry smoothie with salted cheese which was so good! Hoping they make it an annual thing

    Love love love Happy Lemon!!! My usual order: Okinawa roasted milk tea (25% sugar) with boba never disappoints. Sweet enough, pleasant strong tea taste and the boba pearls here are delicious. My mom tired the new Vietnamese coffee (25% sugar) with puff cream and wow!!! Vietnamese coffee is usually too sweet for my liking so I loved that you can adjust it here and the puff cream adds an additional creaminess to it.

    Mango lemon slushie, ube milk tea with boba/creme and grapefruit lemon slushie.
    Kurtis S.

    Overall great 1st visit. Two out of our 3 drinks were a hit! I can say just from walking into the store you are greeted with a pleasant aroma of boba freshness! We each got different drinks; an ube boba (with creme), grapefruit lemon slushie and a mango lemon slushie. I've never had an ube milk tea with creme but it was a fun addition! My wife got a grapefruit lemon slushie which she said hit the spot on a warm summer day and my good friend with his mango lemon slushie said it was slightly sour but overall tasty. We will likely be back as we are new to the area and excited to find a boba spot that we enjoyed so much!

    D6. Ube Milk Tea With Taro Puff Cream and Boba
    Laney C.

    I got an ube milk tea with taro puff cream + boba and it didn't really taste super ube-y. It was still pretty sweet considering that I got less sugar. The boba was pretty chewy but overall this drink was just alright. The wait time was rather long (maybe 15 min?) considering that there was 1 person ahead of me.

    Popcorn chicken, Chili Spicy
    Chrenzoe Christian B.

    No question, this is HAPPY LEMON serving fried chicken. That thing is addicting, dangerously good, spicy and phenomenal. I had to order 3 more for the road! It was that good! I wish I had ordered 10 more! TAKE MY MONEY! One way to start a good service is their smiles. Great job Happy Lemon Team! We went on a non busy hour trying to pick up new stuff for my hamster. So I couldn't really get a rating on the ambiance. But overall, my experience at this Happy Lemon Spot is STUPENDOUS! I will definitely come back and try their other chicken flavors and other new drinks. Thanks!

Plenty of places to choose from on this strip but remembered having a delicious matcha at this place so came to get one from here. Parked in the back and walked to the shop. Tiny entrance to a kiosk outside and one inside. The menu here is so overwhelming because they have so many options. I wanted to try something different but opted for the matcha. My family also got different drinks too. Kiosk is pretty straightforward. Zero human interaction. Since the inside is tiny I waited outside. Our family had several orders so I went in to ask for the ones that were ready. I came back to grab another drink and checked back on my drink that I saw on the table but no one came up to me after they handed me my first couple drinks even though I had asked for an update and could see the drink on the table. After several minutes and getting drinks for other customers I got their attention and got my drink. Matcha was fine. Same flavor as the first time I had it. No space inside to enjoy their drinks but plenty outside in the blocked off street. Service could have been more attentive. 3 people and it was super busy with customers coming and going. Zero interactions with anyone while ordering since kiosks are available. Hoping for a more efficient experience if I visit again.

It's a bit of a mixed bag depending on what you get. The lychee milk tea with 50% sugar and less ice was a 6.5 because you can barely taste the lychee, it was very faint and just tasted like a regular milk tea. The da hong pao milk tea with 25% sugar and less ice was also a 6.5 since it had a really strong herbal taste that I wasn't a huge fan of. The best one was definitely the ceylon cheese milk tea at 25% sugar. It was way more creamy and rich than the others so I'd give that a 6.9.

They have a cute cat theme, a small claw machine, and plenty of parking outside in the big plaza. - MOOMO Mango Pomelo Sago with boba Compared to the older cube cups or even their normal cups, this seems like it holds less drink. It's a creamy mango drink topped with sago, fresh grapefruit, and mango chunks in a special cup. Even at half sweet, I thought it was pretty sweet, but at least it balanced out some tartness. The toppings are good and well distributed, the mangoes were ripe, and the grapefruit pulp added a nice fresh texture. As far as mango drinks go, I'm not too big of a fan, and I've had better and prefer ones mixed with coconut, which this is not. I don't regret trying it and really liked the soft, chewy boba. - Jumbo Fruit Tea with lychee coconut jelly It comes in a big 34oz cup, made with organic jasmine green tea, fresh pineapple jam, orange, lemon, lime, strawberry, and watermelon. At 100% sweetness, I perceived the tea despite it tasting like fruit punch. I like how the bigger cup accommodates for all the slices of fruit, though it's definitely priced accordingly. This is a solid boba tea spot with snacks that I wouldn't mind coming back to whenever I'm in Sunnyvale, just not for their mango drink.
