"Endless Quest is easily one of the top coffee spots in Marin County. The flat white with oat milk is consistently delicious—smooth, balanced, and thoughtfully crafted. The staff are warm and genuinely friendly, making every visit feel welcoming. The space is simple yet beautiful, with a clean, calming aesthetic that lets the coffee shine. A must-visit for anyone who appreciates great coffee and a relaxed, well-designed atmosphere."

"I’ve been super impressed with the coffee at Endless Quest Coffee Roasters. I’ve ordered from them several days in a row now, and today I finally tried their pastries too — also amazing. The coffee itself is top-notch. These guys take their craft seriously: they weigh every espresso, watch the extraction speed, dial everything in… every drink is made with real care. The staff is really friendly, and the whole place just looks great — nice vibe, good music. Even their restroom is stylish and clean, which honestly says a lot. A lot of cafés focus on the front-of-house and forget everything else, but here you can tell they put effort into every detail. Highly recommend this spot if you’re into great coffee, a cool atmosphere, and just an all-around solid experience."

"Finally visited Endless Quest coffee roasters and wow I totally should have been making this stop my go to Marin cafe since it opened! Their pumpkin spice latte was recommended as they make it with real pumpkin (I also had it with oat milk), and it was sooo good. Also tried the Indonesian cold brew and I'm normally someone who has their 'coffee' oat milk and sugar half the cup and coffee the other half, sometimes even just a quarter (idek if I can still call it coffee lol) but wow the cold brew had such a fine taste, very much of the coffee fruit with a dark chocolate finish. Unassuming exterior in the little area by the DMV and Total Wine and Book Passage. I'm so glad I finally went and can't wait to come back and try more of their menu."

"I got a flat white and chose Ethiopian for the espresso, and I could absolutely taste the difference from a typical espresso! It tasted less bitter and a little fruity. I was blown away because I usually can't taste much difference between espresso+milk drinks. My girlfriend also really liked her shakerato, and the staff were so friendly and helpful! Looking forward to coming back"

"Endless Quest is truly a hidden gem tucked inside the Marketplace shopping center. Their espresso selection is expertly curated, and you can tell the baristas really know their craft. Each barista is incredibly knowledgeable about the roasts and beans they’re working with. The staff is warm and welcoming, which adds to the overall experience. The cafe’s minimalist decor manages to feel both modern and inviting, with thoughtful artwork that gives the space a calm, cozy vibe. It’s the perfect spot to settle in with a beautifully made latte. And as an added bonus, the iconic Book Passage is right next door - ideal for grabbing a drink and wandering through the shelves. A must-visit for anyone who loves quality coffee and a relaxed, inspiring atmosphere."
