    Smell sip & savor sign

    Such a cute coffee shop with some really great coffee. I was greeted upon walking in with a warm smile and ordered a hazelnut iced latte. The latte was strong and offered just the right amount of sweetness. It was also perfect for a warm afternoon pickup. Parking is a little tight but I guess you'll have better luck if you don't show up during peak times. I look forward to coming back and spending more time here.

    S3 coffee bar is such a cool spot! I was looking for a local coffee shop but everything closes around 1-2pm. Thankfully, S3 closes at 6pm. I ordered a strawberry matcha and a dirty chai. The staff was sooo lovely they had overflow of drinks so they offered two extra drinks for free. I think it was such a nice gesture rather than tossing the drinks. The drinks are so delicious!!!! The strawberry matcha was my absolute favorite!!! They also have a banana matcha that I can't wait to try! The place is absolutely beautiful. It's quiet, and the decorations are soooo cute!!! Definitely a must visit!!! The bathrooms are clean and spacious. 10/10!!!! Thank you S3!!!

    This is such a cute place, especially for a coffee date. Everything we ordered was good! Highly recommend the blended mocha banana frap!

    Honey rose latte

    Great place for an informal business meeting. Love the energy (even partially empty it feels vibrant) and creative offerings. Had a honey rose late and the meeting went well. Think it's a great place to work. Sadly it's just slightly out of my everyday mileage zone given today's gas prices. You must experience this place at least once!!

    inside seating

    lots of seating inside and it's so cute, service was fast, dirty chai was delicious for $7 16oz! Will def come back again.

    Such a cute coffee shop! Got their strawberry matcha and vanilla lavender latte. The latte had very subtle lavender taste, it was a bit more vanilla forward. The matcha though, it was really good, and they use ceremonial grade matcha. The decor is so cute, and a very spacious place if as the have both inside and outdoor seating plus drive through!

    This is a very cute coffee spot with some speciality drinks and a few bites. The service was pretty quick and easy. I liked how big it was inside and the creative themeing. My strawberry dream was stronger than I enjoy my coffee but the presentation was on point. My daughter liked Ursula's revenge. The Acai smoothie only comes in one size and it was huge. The breakfast empanada was good. They sold out so we were only able to enjoy one but I would get that again. Its a bit pricier than the average coffee shop but youre paying for ambiance and specialty drinks.

    Iced Mexican Mocha
    Eliko S.

    This coffee bar is cute inside and there are lots of tables placed around the dining area & outside for you to enjoy your drinks & treats. Thee are a few shelves of little goodies for sale such as cards & t-shirts as well. The shop was filled with patrons when I walked in, and it seems to be the kind of place where people like to linger. My iced Mexican Mocha was delicious albeit quite expensive - over $10 with tip. It was a nice change from my usual boring iced Americano though. Service was fine. Nothing super exciting or awful, just meh. I really did enjoy my drink though and the place is pleasant. There's parking in the adjacent lot & they have nice bathrooms. They also have a drive-thru option. Mahalo.

    Here's where you drop off your pager and get the coffee out of the little boxes.

    Very nice and spacious, not noisy even though busy. When you're both hard of hearing, it matters! We had a very good Capp and a very good chai, with a fresh bagel with cream cheese. It is convenient to Kaiser Vandever if you have a wait for something. Good parking. The counter guy asked if we wanted real cups, which almost never happens, and I really like a real cup so extra points there.

    Rose Gold 16oz + espresso
    Jiansen W.

    S3 Coffee Bar is serving iced, hot, caffeinated, and non-caffeinated drinks and all day breakfast food in a spacious Christmas decorated interior and a covered wraparound exterior patio. SERVICE Patrons order and pay up front at the register, take a pager, and return to pick up their order at the counter. DRINK 4/5 Rose Gold Latte 16oz + espresso: Topped with 24K gold glitter, and missing rose petals, rose and honey syrup lightly flavor and highly sweeten this almond beet tea latte. I bought a double shot of espresso to counterbalance the sweetness.

    I love the S3 at this location. I've been here a couple of times now and the staff has always been friendly. The only annoying part is that parking can be a little tricky. It seems to be a very popular drive thru coffee bar eh un explains it. I haven't tried any of their food items yet, but the coffee was fantastic. I also love the cute design details they have on the inside. Its a great spot to sit and study, I'll be back for sure.

    Almond Tea
    Yvette G.

    Tea was GOOD. I'm huge tea drinker, never had almond tea before but it was SO good. The cafe is cute! Walked from discount tires while I waited. I love that they have light food options. They have outdoor seating too.

    Mermaid toast
    monica c.

    Cute 2D coffee shop with unique drink selections and some foods. I usually come for their seasonal drinks. Always gotta have a sit down inside the shop so I can enjoy the atmosphere. There's a good amount of seatings. Their biscoff latte was my favorite. It's strong too! I have ordered their mermaid toast before because it was pretty-looking. I was expecting a sweet flavor coming from the cream, but it was just regular cream cheese.

    Yes

    Can I get the rainbow latte iced?

    The latte art can only be made on a hot drink. However, if you would like a colorful drink iced, you may always order an iced blue or pink matcha or island, they are seasonal drinks that you can still order them off them menu if you check with out… 

    Wifi & outlets for customers?

    We do have 2 outlets along the bar and free 90 minutes of WiFi.

    Can you please open the shop at 6:30am?

    We do have a few tables at the patio with 1 hour limited WiFi. However, we don’t have any outlets at our patio. If you don’t mind not having outlets and doing work at the patio, then you should come. Note: we are in front of the bus station so… 

    Who roasts their coffee? Do they offer different varieties?

    We roast our coffee in house.

    Why does it say they are open at 6:30 am but I just drove by and its not?

    Our drive thru is open :) the inside is open for takeout everyday from 8-3. Sorry for the confusion, Yelp won’t let us input multiple opening times, but we did added our special hours on our Banner Message.… 

    Do they offer decaf drinks?

    Yes, we can make any drink with decaf espresso base

    Are all the drinks being served in togo cups because of covid? And if yes, is the presentation still the same?

    The presentation is still the same on iced drinks and if you like latte art on our hot lattes, please let the cashier the cashier know and we will not place a lid on your hot drink.

    Does this place get real packed for special drinks like the pumpkin latte that will only be sold certain days?

    Yes, only this Saturday 10/16, Sunday 10-27, & Halloween Day 10/31. We hope to see you then...

    Are rainbow lattes only available on weekends still?

    They are available everyday now :)

    Did the menu change? I saw blended drinks on some yelp pictures, but was just informed you do not have them.…

    Yes, we no longer provide blended drinks on our current menu. We also have seasonal drinks that changes constantly. Unfortunately, we cannot removed any pictures not posted by us. Sorry, for the confusion. You may always check out our current menu… 

    Vegan friendly options?

    Yes, you can always modify our Avocado toast (no cheese), acai bowl (no drizzles), and we also have dairy free milk options.

    Is there an outdoor section? Is this coffee shop dog-friendly?

    I've seen some people bring their dogs inside to grab a coffee but I haven't seen anyone stay with them. There is some seating outside but it would only be like two small tables and chairs.…

    I've been trying to eat more healthy and have been obsessed with açaí bowls! I always pass by here…read morebut never stopped by until now. Ordered ahead via the app and it was ready on time, the store was completely empty on a weekday right after opening. The girl working was nice Got the Everbowl (regular size), and it was big enough to split with my sister. I loved the açaí base, it was the perfect consistency. Love how there's also so much fresh fruit and crunchy granola. We also got the avocado toast, and I liked the flavoring but wasn't a fan of the honey. The bread was also a bit burnt in the corner. Everything was a bit pricey but good. I will definitely come back for the açaí bowls!

    Everbowl is a never bowl for us. We ordered 2 large whateverbowls and a strawberry banana smoothie,…read morewhich wasn't horrible but just tasted like slightly banana-y milk. Bases for the bowls were icy and the number of toppings is limited. Bases are not packed down so my bowl had large air gaps and still wasn't filled to the top. Employees were chatting it up with each other despite a good number of customers in the store waiting. Blue bowl is a lot better value and quality of ingredients, with super creamy bases and unlimited toppings which get jammed down into the bowls. We were in the area and gave Everbowl a try, but won't be coming back.
