    Iced Vanilla Latte
    Rimmi S.

    Got the iced Vanilla latte with extra syrup. Shot was pulled great but the syrup was pretty weak considering I got extra. My latte was also lukewarm Very homie inside, lots of tables and fast service. They have lots of food options on display + made in the make and all looked very yummy. $7.25 for a medium.

    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.

    My refreshing iced mocha with oat milk, 2 & 1/2 pumps of coco and whipped cream!

    This summer, I've decided to cut back on my coffee intake. I've been doing pretty good, however, I had a strong taste for a mocha iced coffee so I decided to patronize my local coffee shop, Eon. It was a taste of perfection, not too sweet and not too bland; oat milk & 2 and 1/2 pumps of chocolate! Thank you Eon for getting it right!

    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!!

    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.

    Iced Matcha Latte (Soy Milk)
    Kyra K.

    My coworker recommended we meet at Eon Coffee since it was in the same area that my dinner plans were in. It worked out perfectly since it was a laid-back, quiet, and spacious atmosphere. The cafe is quite modest and bigger than we expected. My companion and I came on a weekday afternoon since we were both working from home. There are plenty of tables inside and outside along with outlets and WiFi. Music plays a little loud so keep that in mind. The menu is posted with typical coffee and teas, specialty drinks, and food. Ordering is simple--done at the register and your name is called out when your item is ready. We found the service to be efficient. My companion and I had an Iced Matcha Latte with Soy Milk while my coworker got a specialty drink. The matcha was surprisingly good! It was sweet and creamy with the matcha being more of an aftertaste. It was good for the size and price point. My coworker said his frappe was solid. I'd try the other drinks here. For those in Hayward, I recommend Eon Coffee to study or work at. This is a one-stop shop for it all. I'm rarely in Hayward so don't see myself coming here often but I'd recommend it to others. Plus parking is free in their spacious lot being it's located off Hesperia Blvd.

    Italian Cappuccino

    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.

    It's a good place to work on your laptop or have a quick business netting. Deserts selection is reasonable and coffee is quite good.

    The Olive Market - Our best selling pastrami "Market Special, Loaded"

    The Olive Market is a must-try..Believe the HYPE! I saw this place getting a lot of attention on…read moresocial media and I had to see it for myself. First of all, the ambience of this shop is really cool. They have a bunch of specialty grocery items all around the store of stuff that I've never seen before. The staff was super friendly and everyone really seemed passionate of what they were doing. It gave off a homey/cozey vibe. The sandwiches my wife and I tried were the Loaded Market Special, Market Special and the Padrino. Everything was well put together and all the ingredients complemented one another. Our favorite out of the 3 was the loaded Market Special. If you like a little spice I would highly recommend trying this one. The lettuce and sauce balanced out the saltiness of the pastrami and the bread was fresh. The cheese was nice and gooey and gave off a perfect pull. The size of the sandwich was perfectly sized. Not too big and not too small. If you're on a time crunch I'd recommend ordering ahead on the phone as they can get a little busy.

    We decided to try this deli after seeing it all over TikTok. The sandwiches looked incredible, and…read morewhile they're definitely on the pricier side, the reviews made it seem like they were worth the splurge. Unfortunately, we were pretty disappointed with our experience. We ordered the exact same sandwiches we had seen featured on TikTok, but what we received looked noticeably different and honestly wasn't nearly as impressive. The sandwiches were fine, but for the price, I expected a lot more, especially after seeing what was advertised online. I also found the experience at the sandwich counter a little underwhelming. I've seen several Yelp reviews mention how welcoming and friendly the staff are, but that unfortunately wasn't my experience. No one acknowledged me at the counter, even though they weren't particularly busy at the time. It just didn't feel very welcoming. Overall, I don't feel like the price reflects what you actually get in person. Maybe we caught them on an off day, but based on this experience, I probably wouldn't go back.
