    Review is based on coffee and not on smoothies/food. I went to Eon cafe late afternoon and it was fairly busy. Ample parking space. We got love latte and vanilla latte. Love latte had a very strong artificial taste from the syrup they use. I would avoid it next time. Vanilla latte was decent. Service was good, however the place seemed run down and not clean. They had good music playing, perfect for working. I would go back and give it another try since there are not many cafes in Hayward.

    I came as they were opening. Nice dark roast latte to start my day. The coffee was made quickly and I appreciated that. They also have a food menu. Standalone store with inside and outside seating and a private parking lot. Please come and create your own adventure.

    I got the latte love - in English toffee flavor and my husband got a vanilla latte. The latte art was very cute and coffee was hot however I did not like the flavor in the latte love it was butter and artificial tasting. The vanilla latte was good. The place has a lot of seating and soft music so it's great for working. I was sad that they didn't give me a little biscuit with my latte like I see in the pictures. The place was also not very clean when we went. I wonder if they were under staffed since we did go in Veterans Day. Either way, I would come back to try their other drinks.

    I have drove by this place and never tried it til today. Nice coffee shop with many tables and chairs for meetings or just having coffee. There's tons of various coffee selection in their menu. They have awesome tentative service and the wait isn't too long for the coffee. They also have some selection of food and snacks to choose from. If you want a coffee shop to hang out in that isn't slammed and busy like other coffee shops EON is definitely the place to go.

    it was my first time coming here and honestly, I'm gonna say that it was a 10 out of 10 as soon as I walked in the guy at the front was super Duper nice I didn't get his name, but he was really really nice and the coffee actually turned out to be so good. I got the gingerbread latte and it's literally so delicious. At first, the coffee spot from the outside looks kind of like like maybe it wouldn't be too good but when you go inside, it's so cozy and people are studying and working, and you just feel cozy and at home and the coffee is also cozy and sweet yummy everything. I didn't have a chance to sit inside but next time I will. okay so the guy who helped me at the cash register is tetsu!!! he is super nice gave me the best coffee recommendation and even helped me pick out one of their instant ramens!!!! thank you tetsu!!

    Chicken salad sandwich

    Amazing food and service. Very friendly and extremely fresh. Wouldve received 5 stars if i didnt find a bone in my chicken salad sandwich. Took it out and scarfed the rest because im a whore for eons sandwiches.

    I always used to love coming here for my usual Mexican mocha and a bagel with salmon cream cheese. Recently I went and I was charged the same price for the cream cheese as the bagel. I had asked if that was a mistake and the owner said it wasn't and that salmon prices went up.. to me that sounds like a bogus reason since the amount you get isn't even enough to spread on both sides of the bagels.

    I dropped in because I was already in the area picking up a mochi order, so I figured--why not grab a coffee? I love checking out new coffee spots, and this one immediately reminded me of the cozy cafes I used to frequent back in my SJSU days. Makes sense, since it's close to a local college campus. The parking lot was a bit busy (probably because of a flea market happening across the street), but the café itself wasn't too crowded. Service was quick and friendly. My husband got the caramel frappe, and I asked the cashier what he recommended. He mentioned the macadamia iced latte--said it wasn't on the menu board but super popular with regulars--so I gave it a shot. Later he mentioned he's more of a lemonade person than a coffee drinker, which honestly made me smile--recommend what you enjoy when people ask haha. I asked about the mulberry tea (which was actually what I had my eye on to begin with), and he said it was solid. Definitely going for that next time. The macadamia latte was... fine. Not bad at all, just not a standout for me. But I love the vibe of the place, and I'm excited to come back and try something new. Mulberry tea, you're next!

    It's been a minute since I've been to Eon. Located across a popular community college in the area, this is a prime spot for students who are preparing for finals or doing homework due to its location and free WiFi. When I went early during the weekend for a quick breakfast, there were plenty of open seats but not too many with a working outlet. I was helped by someone at the front, a friendly cashier. They have the usual coffee and tea options, as well as paninis for a quick bite. I got a chipotle chicken panini, which comes with a side of chips and a pickle. The sandwich was flavorful, and filling enough for a few hours. I did note that the water I got tasted a little funny, definitely had more of a tap water aftertaste but not a big deal. Overall, the location, friendliness of staff, and price point would make this a cafe I would recommend to anyone in the area.

    Really smooth cappuccino with a nice, balanced taste. The milk was creamy without being too heavy, and the espresso came through just right. Plus, the latte art looked great. Overall, just a really enjoyable cup.

I had been to the church before, but I didn't remember the massive coffee hangout there! It's so spacious and offers plenty of seating. How long has this place been here? I wish it were closer to where I live in San Jose! I could easily imagine sitting in one of the comfortable nooks, studying or grading papers. It's also a fantastic spot to meet up or chat with a group of friends. It was definitely a nice place for a date! When we walked in, there were hardly any available seats, but the line at the counter wasn't long. We found a quiet corner to sit and enjoyed our breakfast. I ordered a hot latte with maple syrup in the name, though I can't recall the exact name. It paired nicely with my pastry. The almond croissant I ordered was delectable, with just the right amount of sweetness and flakiness. My partner enjoyed his cappuccino and savory bacon croissant. We walked up two steps to the restroom and were surprised to find more seats and tables. I wish I had noticed that area when I was looking for a place to sit. Oh well, it was comfortable where we were. The girls should have more playdates with their cousins so we can come here more often. Is it really called a "playdate" when the kids are 12 and 15, and their cousins are between 21 and 30?

The salted maple latte was just ok... sadly it looked better than it tasted. I wasn't a huge fan of their espresso as it left a very sour after taste, even with the sweet maple syrup it wasn't very pleasant. Good espresso should be balanced and coffee forward, and I didn't get that. Almond croissant was great, but I was a bit disappointed in their coffee. Ambience is great for studying or getting some work done.

Although the tofu was a little dry and lacked some flavor (had to use sriracha), the chicken banh mi was flavorful and well done, though there was quite a bit of chicken. The fruity matcha with boba was also pretty good as was the Vietnamese coffee, though the coffee was on the strong side. They also sell sesame balls, French bread, and other baked goods as well. We recommend ordering ahead since there is a good amount of people coming in each morning. They take phone and online orders. This is a nice sandwich spot and they have 3 round tables with 4 seats and 4 rectangle tables with 4 seats or so. There is plenty of seating to go around.

The inside interior design is something more akin to a 7/11 grocery store, with a wide countertop displaying colorful and tasty looking Mochinut donuts with the back area for food options. The space is peppered with some two or three person tables as well, with a small display shelf helping to delineate where the line to the cashier starts. Regarding the viet coffee, this one was particularly strong, with a definite higher proportion of coffee to condensed milk that doesn't offend but also risks being a bit TOO strong (wild to say that when all viet coffee at its core is strong). Overall, it's conveniently located, but I think I might prefer to go further south for something with a more balanced taste profile.

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. I was expecting them to do it if I asked but she was so kind. She offered me to keep the first drink and remade a new one for me with a huge smile. Excellent customer experience save. 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. Wish we could choose sugar level but nothing seems overly sweet here. Only complaint is that the drink lids ripe every time you insert a straw. They need nicer plastic lids.

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.

Was so glad that she was able to open up her own bakery/cafe to feature these and additional Asian-inspired desserts for the Bay Area to try! MACARONS. I've been a fan of these Macarons for years, and what first drew me in was their adorable themed designs for holidays and special occasions like Lunar New Year, Valentine's Day, Halloween, Thanksgiving, and Christmas. While their character macarons and classic rounds are super cute, what keeps me coming back is that they actually taste amazing. There's nothing worse than biting into a beautiful macaron only to find it's dry, but that's definitely not the case here. Their macarons are consistently moist, flavorful, and fresh, with the perfect texture every time. It's the best of both worlds--beautiful designs that are almost too cute to eat and quality that lives up to the hype! JAPANESE SOUFFLE CHEESECAKE. My first Japanese soufflé cheesecake experience was from a commercial chain, and while it was light and fluffy, it doesn't compare to Always Yours Bakery Cafe. Their cheesecakes are THIQ in the best way possible--rich, dense, creamy, and still have that perfect jiggle. My absolute favorite flavor is the Ube! Ever since discovering them, I'd much rather order a whole cheesecake from here than pick up a standard birthday cake from the grocery store. It's always a crowd-pleaser! DRINKS.

What really stole my heart was the Earl Grey Creme Brûlée Milk Tea! "Creamy earl grey tea with your choice of milk, topped with our housemade salted cheese cream, torched sugar, and creme brûlée pudding." It's def a unique combo I haven't came across any other milk tea shop yet til here, and given that it's a bakery, I figured their creme brûlée would be amazing--and it FASHO IS! I recommend it with oatmilk and less sweetness to help balance all the flavors. _______________________________________________________ --- S E R V I C E --- The staff is always so friendly and accommodating, and you can tell they truly care about their customers and the quality of what they serve.

When you first walk in, you're greeted by a display case filled with beautiful desserts, and I definitely recommend taking a look at the other treats on the menu besides the cheesecakes.

The dining area is small but thoughtfully designed, with marble-inspired walls, pops of greenery from the plants, and a purple neon sign that ties everything together.
