    My receipt
    Paul K.

    Love coming to this flagship store. Always bustling with a line that moves quickly. Freshly made items being prepared in the open kitchen that is fun to watch. I had the quad Mexican Mocha with a cup of Ellenos yogurt with granola and blackberries and raspberries today. All were good and filling. They do a great job with keeping the large dining area tables clean and wiped down. Definitely will return

    The probiotic overnight oats here are my favorite, it's sooo good! The honey cardamom and Carmel silk lattes are the best too. Wait times can be long here, but they have an order online option. There's plenty of inside and outside seating.

    Update; After leaving my only 4-star review for Mercury's Coffee I was quickly contacted by the manager to address the concerns I had in the review. I did not expect that at all since it was a 4-star review. I have to update that review to a 5-star. This is a stellar establishment that actually cares about their customers and customer service. I was already a loyal customer since all my previous visits were great, and I'm an even bigger fan after experiencing the upstanding business culture of this company. Thanks again for hearing me and making my day! I'll be back next time I visit my family!

    Turkey Havarti
    Meralina M.

    My friend I didn't realize this place was such a craze, so when we saw the long line we were kind of taken aback, and then wondered if it would be worth it at all. IT WAS SO WORTH IT!!!!!! First of all, the staff was incredibly friendly and helpful. And don't let the line deceive you, the service is quick. My friend got a blonde Hawaiian and she loved the balance of sweet and macadamia nut. I got an iced chai with oat milk, and it definitely tasted like Oregon trail, but honestly, it was still good. We had a couple of croissants and some lemon raspberry madeleines, those were also good. But the true star of their menu was the turkey havarti!!! The bread is baked fresh in house and is so perfectly salted and bouncy. The garlic aioli they use on the sandwich is also drool worthy, and they give a good amount of meat! The sandwich looks small, but she is MIGHTY! I can wait to have that sandwich again!

    This is the only Mercury Coffee that has an in-house bakery. I enjoy coming here for coffee and something sweet post dinner when I'm on the Eastside. I remind myself that while they make their own croissants in-house, they are not a patisserie. Once, I reset my expectations, then I can enjoy the baked goods on their own merit. So far, I've enjoyed the raspberry lemon scone, cinnamon roll and the twice baked chocolate almond croissant. The ham and cheese was okay and was sampled prior to my resetting my expectations. Portions are huge and definitely shareable. The friendly customer service has been hit or miss. Sometimes it's friendly and helpful and sometimes not so much. There's plenty of seating inside and outdoors. If you sign up for their rewards program, you get $10 to spend on a future visit.

    Mercury coffee is consistent and delicious every single time. It's the most amazing experience because I feel like a kid at a candy store. All the treats and devious drinks! Heaven is on earth after all.

    I'm a huge fan of the aesthetic, the drinks and the food, both in quality and flavors. The closest location to me is an hour away so when I go, I buy everything and try to enjoy my visit as best as I can. Service quality is honestly spotty - for example, the last time I went, the cashiers were all chatting and seemed to be very relaxed, despite it being busy, and they made me feel like I was inconvenient to them. Not overtly rude but definitely giving those vibes. Another issue is seating availability, but usually you can find a tiny spot to settle on.

    Delicious baked goods
    Treena C.

    This was a nice surprise. Nothing too flashy from the outside but open the door and among other items, the biggest fluffiest croissants are just sitting there waiting for someone to eat them. I loved their croissant combos- -croissants with peppery bacon and beechers cheese, -turkey, provolone and Beecher's cheese croissants as well as creative quiches and sweet treats. Have you seen their cinnamon buns? I chose a croissant with bacon, egg, tomato and cheese. They warmed it up and it was above and beyond! Lots of fun treats here. They have their own coffee beans and they are delicious. So much flavor! They make their lattes with the Rising beans and they are worth purchasing. Service was extremely friendly. We will be back many times over.

    Fusion Mocha
    Brian L.

    Overall: Mercury coffee is a fairly standard coffee shop, has a variety of coffees and pastries. Only ordered 1 coffee from here, but unfortunately it was far too sweet for my liking. Food: I ordered the mocha fusion, I understand that it is supposed to be a sweet coffee, but it was just too sweet to handle. This drink's recipe needs to be reworked. Service: The service is fast, they get your coffee ready quick. Ambiance: Fairly standard coffee shop, as a couple of seats in the back with a bar style table where you can sit.

    These are what a croissants are supposed to look like. This is an image stock from the internet and NOT from Mercury.

    Croissants are supposed to be layered and flaky. Mercury's croissants are not those. It's just a piece of bread that anybody can make. Either they forgot how to make croissants or they don't care how to make them anymore. I once complained a year ago about their croissants and stopped going but I decided to give them another chance and they have once again failed. Management or the owner's need to do a reassessment on their bakery. Just advertise it as "bread" because they aren't croissants.

    The roasting area. They were making pastries too!

    My friend and I were on a small scale excursion around Issaquah. I wasn't sure about my next stop after some walking on a pedestrian/bike lane but suggested we go to a coffee shop. My friend then took me to Mercurys Coffee, which is a chain in the east side and a place where my friend likes to go occasionally. I thought the coffee is good and the staff were friendly. I ordered iced caramel macchiato, half sweet. Service was fast too. I liked how there are plenty of seats, and even with the place almost full, we were able to find a seat outside in the shade. I also liked how it's open until 9 pm so you don't have to worry about being there for a really long time. There are two gender neutral bathroom which is kept clean.

    Vanilla Latte and Bacon, Egg & Beecher's Flagship
    Steven T.

    One of my girlfriend's favorite coffee spots in Seattle that she wanted to show me. The coffee was good - sweet vanilla flavor, but not overpowering and could still taste the coffee flavor. The sandwich was absolutely amazing. They make their own rolls in house that were buttery and flakey like a croissant, but slightly firmer. Paired with famous Beecher's cheese, a little bit of mayo and maple syrup, this elevated bacon egg and cheese was one of the best breakfast sandwiches that I have ever had. Forget Starbucks and come check this place out when in Seattle! Entrees: Bacon Egg and Cheese Drinks: Iced Vanilla Latte

    Roasting onsite
    Kamleshwar C.

    This is always my go to cafe atleast once whenever we make our annual Bellevue visit. Big and open space .... Roasting onsite and bakery is full of stuff which never goes out of stock even you visit in the evening. Blonde Hawaiian is my fav.

    Does this place sell Lotus Energy?

    Hi Bunny! Yes, we offer Lotus Energy at all of our locations.

    Has the company taken measures to protect the baked goods inside within the service island? Are the goods still right up against the glass/plastic barrier without any covering?

    😷😐 haha I've been here many times. They do there best to protect the food with plastic wrap and if it's not wrapped it's behind the case. Perhaps you'd prefer a place that just uses photos to display the food. 🤣 I feel like they do. So...

    It's bubble tea and waffles. You can't really expect a Michelin star meal here…read more That said, when there is a line it goes pretty quick when it's mostly regulars, and only gets bottlenecked by people who have never bubbled their tea or bubbled their waffles before and don't know how to order. Or who haven't used a touchpad POS I guess - which is surprising but it happens. ...hell I work in tech and only this month used my phone to pay for a thing at a POS but I digress. Never was a priority. I've ordered there consistently. I usually get the same thing. I'm more of a no boba milk tea person. Service is consistent. Prices are decent. I guess the low reviews are people who are expecting Din Tai Fung levels from a small place in the mall? Then again I don't boba I only milk tea so what do I know. People are super picky about their balls and how they want their balls to taste. I say set your expectations on your balls and stop being a ball buster. Good grief people have gotten so artisinal about their boba balls it's like they expect each one to be flow in individually by a drone or hand selected and blessed by the Pope. Or do like I do and go for the milk tea and not worry about it. Can't go wrong with milk tea. Or maybe the low reviews are people who are over complicating their orders and expect Frank Lloyd Wright and Gordon Ramsey both to be back there assembling their bevy for $7. For what it is, and for the price, I have no complaints.

    TL;DR: for such a large chain, this place is really disappointing. Boba is cooked unevenly. Sago is…read morenothing but a huge goopy clump. Not worth spending $10 on a cup here. I thought I'd give this chain a try and I was very disappointed. Parking: mall garage, free. Atmosphere: no seating, long lines for ordering, waiting for your order to be completed is longer than waiting in the line (I presume it is because they fill mobile orders at the same time). Menu: posted on the back wall above the register, also a smaller menu at the beginning of the ribbon divider. Service: order and pay at the front, wait for your order to be announced, grab your own straw. Mango Sago Smoothie: I requested 30% sweetness and it was still very sweet but that wasn't the worst part--it wasn't until I reach the bottom of the cup that I saw the sago was nothing but two large coagulated clumps. It was clearly poorly made and not fresh. The mango tasted mediocre and was nothing to write home about. The boba was also very unevenly cooked and was mushy on the outside and rubbery/hard inside. I noticed this on the first sip and wasn't going to stand back in the 10 minute queue to get it remade. I'm all for bubble tea joints and I honestly thought the drinks would be better quality for a chain so large that I hear about.

    My husband and I came on a Saturday afternoon, after finishing working out together in the morning…read morewhere it wasn't really busy. I got a 32 oz "Slim N Fit" with mango flavor and my husband got a 32 oz "Lean Out" with chocolate flavor. My Slim N Fit tasted good while my husband said his had a little too much peanut butter. Overall customer service was good, little wait time... we had to park at the plaza nearby and didn't have to pay parking. A good spot for an after workout smoothie. Would come back again.

    My friend and I walked over to Emerald City Smoothie in Downtown Bellevue after doing barre class…read morenearby. This was my first time at Emerald City Smoothie in ten years and my first time at the Downtown Bellevue location. The interior is fairly small with only a few tables to sit/stand at and so it's mostly a takeout place rather than a place to meet with friends. Emerald City Smoothie has a wide menu and categorize their menu into five categories based on health goals: "Boost My Immune System", "Help Me Lose Weight", "Go Green", "Bulk Me Up" and "Nourish My Body". They also have a menu just for "Boosters" which cost extra and include everything from antioxidants to bees pollen to creatine and fat burner. Lastly, they have a Secret Menu which includes Banana Creme Pie, Matcha Green Tea, Maui Paradise, Mountain Berry Blast, Orange Creamsicle, Piña Colada, and Peanut Butter Cup. I'm pretty sure their secret menu is just drinks that don't fit into the other categories (or ran out of room for), because they had these same drinks on their menu ten years ago. I ordered the MATCHA GREEN TEA (16-oz) off the secret menu. This smoothie has soy milk, matcha, non-fat milk, and whey. For $7.44 (including tax), this was pretty pricey for a "healthified" matcha Frappucinno. They obviously don't use high quality matcha as the matcha color was on the yellow side and the taste was quite diluted and bland. It mostly just tasted like sugary blended milk with little to no matcha flavor; I was honestly disappointed, but drank it anyway. My friend got her favorite NUTTY BANANA (sub vegan protein) which has banana, peanut butter, protein, and nonfat milk, which is probably what I should've gotten instead. She also ordered a PB&J and MANGO MANIA for her family members which are also supposed to be decent. Lesson learned, stick with the fruit smoothies. Service was good- the baristas are friendly and efficient and we got our drinks within 10 minutes after ordering. Overall: 2/5 for drinks, 4/5 for service, 3/5 for atmosphere
