Red Rock Coffee

Best place to do startups networking here. 2nd floor is pretty packed so try to get early on weekends here to grab your seat. coffee is kick-ass kind of... The best coffee probably in Bay area.

This place caters to laptop squatters, anyone who wants to go to a cafe & spend lots of time working. Top floor packed with desks and outlets, and the WiFi is pretty fast. The coffee is just fine.

Great working space on the second floor. Free Wi-Fi and lots of outlets available.

This is the best place for coffee on Castro Street in Mountain View with plenty of seating inside and outside.

Want to swim in a soup of startup geeks? Come in here for your daily dose of "It's kind of a Groupon for..." and "Facebook API is all f...". I always see fellow Y Combinator founders in here.

Try the Honey Lavender Latte !!!

The Las Palomas family beans cultivated by Pache & Bourbon from Guatemala we're available as a cold brew . This brew style hones in on semi-washed bean flavor; earthy spinach and dry, semi-sweet coco .

I asked for an iced pour over , and while they don't make it, they were super accommodating and it was one of the best I have ever had.

The house blend is a mix of Heirloom Ethiopia and Nicaragua beans. The cup is balanced, with a fresh mouth and acidity of acai berry that is matched smartly with a dark chocolate body.

Check out the area upstairs for a nice and mellow work environment, and the view doesn't hurt! The water was just to die for!

Four Barrel Coffee pour overs. The barista is very helpful in helping you select the coffee of your dreams. Just describe what you are looking for and they will do the rest.

Today's cold brew blends "Andino" (Caturra farm in Columbia) and "Java Luetic" (Typica & Ateng- Java Sunda ). Cup has a soft mouth with a complex yet clean body. Watermelon , wheat grass , pistachio .

Great coffee ! I would highly suggest the single origin bar . The baristas are all very skilled and knowledgable and will make sure that your shots are perfect.

This guy sits on multiple chairs with his feet up. All the time.

Productivity: 4 stars. The classic startup coffee shop on Castro st downtown. 2f excellent for light coding/work.

This has become my go-to place when I have some time to kill before my Caltrain arrives. Good coffee & espresso drinks , iced tea and a good variety of pastries for those wanting to indulge.

Excellent coffee . Great service. Expensive croissants . Went back for the coffee every morning for a whole week. Haha

Great coffee and a great place to talk or work (upstairs ). I'm a big fan of their latte and iced latte .

Vegan cookies and fantastic coffee ; not very communal, but can get fantastic buzz from the general notyetrepreneur vibe as well as the coffee . Plenty of outlets for working in your alterna-office.

Espresso , croissant and a nice space to work at.

Really great flat white !

Best place on Castro to chill out with friends, get some work done, meet fun geeky people or enjoy the live music on weekend evenings. Love the Chai Mocha here.

They do a ton of open mic night type events upstairs making this a difficult place to get something done in the evenings.

Not sure about American standards, but by my European standards their "small" is enormous, and everything else is comically large.

Lots of room for quiet coworking on the second floor!

Filled with aspiring startup founders, outlets, strong wifi , and slightly pricey drinks. Good place to do work

You can overhear people catching up on life with their loved ones, startups discussing fundraising, etc. Makes you realize on so many levels that whatever it is that you're facing, isn't unique to you

The Qorema Heirloom beans of Ethiopia were prepared as a 12-hour cold brew . The brightness of the bean is captured but acidity is softened somewhat. Back & side tongue mouth flavor of chocolate orange

A great cafe along Castro street. There is a little crowd on 1st but comfortable place on the 2nd floor.

Red Rock is my go-to spot for coffee . The people are friendly , the place is cozy , and the lattes are great!

You should know this place is owned by the Highway Community, a church . On the bright side all the profits go to charities , making them almost a non-profit

The barristas are really knowledgable & super nice. If you want to learn more about coffee varieties & preparation order a pour over coffee and ask them to tell you about it.

Really nice place to work at. Very fast WiFi connection which is unusual here. I completed lots of work in here today :)

Really friendly service and nice single origin . Good for working if you can get a seat upstairs .

Great place to work on a laptop, circa 2008. Since then, the coffee roast changed (badly), service declined, baristas are inexperienced and dogmatic, and wifi is usually borked. A failed experiment.

Use Clover milk , which is organic and local to SF Bay Area.

A cute little place off Castro Street with a nice area to have a meeting or bring your laptop to work upstairs .

If you do your best coding with a beer or margarita at your side, you'll have to BYO , sadly. Don't despair -- most blenders fit in backpacks.

Great place to get some work done. Has an entrepreneurial and techie feel right in the heart of Silicon Valley. (via @elatlboy) Read more

Get your coffee and go upstairs to work! :) A coffee shop that buzzes with tech conversations! Love working here..

Single origin bar is good for a wide range of different beans for pour-overs. Very knowledgeable staff .

To sign up for the open mic on Monday nights, show up at 6:30 and put your name on the list. Also, don't nix the whipped cream on your order-- it's made in-house!

Great place to do work. Plus a great environment to relax and have meetings. Recommend it 100%

Go upstairs for great study/working place!

Skip the line and get an exquisite single-origin espresso (or quick drip coffee ) from the side bar when its open.

Outstanding coffee , and a funky place to hang out in the middle of happening Mountain View.

Come in during August and try the honey lavender latte ! Simply the best!

Get espresso from their single origin bar . Four Barrel coffee served.

Their espresso drinks are awesome! Keep in mind their coffee is more on the acidic side.

This place can get crowded but it's a fun place to work if you can find a seat upstairs .
