Where have you had the best (or most atmospheric) coffee?

I would say Cambodia :) I had my very first taste of Vietnamese coffee in the strangest coffee house I've ever been to

I had it in front of Kurukahveci Mehmed Efendi Mahdumları, a local Turkish coffee producer. I drank my coffee smelling the awesome hot coffee beans. Here is a receipt for delicious Turkish coffee http://turkeydesk.com/how-to/making-turkish-coffee/. My second experience was in a small village in Tadjourah, Djibouti. It was awesome mocha, which came from Ethiopia.

at Sequoia National Park, fresh brewed off the camp fire, walking around the woods. 

Hey Sarah, this is a fun question! For me, back in 2008 in the town of Safranbolu Turkey. I was a nanny and it was my first time abroad and I was just trying to take it all in. We sat in this cafe (Arasya Boncuk Kahvesi) and had a very strong, beautifully presented cup of Turkish coffee. 

Everywhere. Actually coffee is a good idea whenever you are travelling. Vienna at Café Central, Paris at Le Relais Saint Germain, madrid at in Puerta del Sol, San Francisco @ Lori's Diner with breakfast, Kuala Lumpur at Old Town White Coffee @ Cheras Midah in Little India, Zanzibar Chumbe Island, Kenya at Nairobi, Istanbul, Sark Kahvesi in grand bazaar, Hiroshima at Tully's Coffee.

The best coffee I ever had was in Rome in a little coffee shop near the Pantheon called Sant'Eustachio Il Caffè. It's really well known there and it's truly wonderful.

I also loved Vietnames coffee hot with condensed milk or cold. I even brought home some coffee and the pot to make it.

Turkish  coffee is also wonderful and if it comes with a future reading even better 

Agree with Vietnamese coffee.

There are good local coffee in several countries in Southeast Asia.

I was surprised for free flow coffee at my hostel in Penang, Malaysia.

I love Laotian coffee which come from Bolaven Plateau in Southern Laos both from nice restaurants and at local food shops.

I tried Luwak coffee in the plantation in Kintamani, Bali, Indonesia. Good!

Now in Thailand, nice local coffee beans from the North are widely used in many coffee shops. Famous brands such as Akha Ama and Doi Chang.

Holy cow, it's gotta be nitro-charged cold brew at Stumptown Coffee Roasters. A wonderfully smooth chilled coffee with the texture and look of a pint of Guinness. It has a slight sweetness to it without any sugar, and it has a thick mouthfeel without any cream. Couldn't be better.

I'm typically more into espresso-based drinks like cappuccino or cortado. But still, this was amazing.

Hidden House Coffee in San Juan Capistrano, CA. It's tucked in by the train tracks in a historic house with a porch. Grab a cup and sit under the pepper trees or on the porch. Afterward, wander Los Rios Street, where some of California's oldest houses are situated.

Thinking Cup in the North End of Boston

The most welcome cup of coffee (and Lamington cake) was served in a little outdoor cafe near the Kuranda rainforest in Queensland Australia. We had trekked for about four hours and were tired and thirsty. It was heaven in a cup!

Beach Bum Cafe, Honolulu.

Mirablau in Tibidabo, Barcelona Spain.  

It was a clear beautiful day and I sat at the top of the world and looked down at the city all the way to the sea. You could see Basílica de la Sagrada Família and the Cathedral,it was breathtaking.

There's a little town in Northern France called Saint-Malo.  By Normandy, it's a cute sea town surrounded by city walls.  So nice grabbing a coffee and sitting on the wall and enjoying the ocean

1300 masl next to the coffee plantations, during heavy rain, beans roasted by the same farmers in Satipo, Perú.

I agree that Hanoi takes some beating, but Phnom Penh in Cambodia also has great coffee.

In Naples

There's a coffee shop in downtown Newport (Oregon) that my family loves. You can drink your cup of coffee on a covered patio or on the deck. The river is below. 

It's located right near the bridge where the river dumps into the Pacific Ocean. The sea lions love this area and they are always chatting away with one another. 

It's a lovely place to have a cup of coffee. The smell of the sea and the sounds of the sea lions... it feels so "Pacific Northwest" to me. 

I vote for Cafe Milagro in Quepos, Costa Rica.  Located right on the Pacific,  Milagro has a large roaster in the center of their café, freshly roasting Costa Rica's finest all day long.  Not only is the aroma of the roasting coffee heavenly, but beans go right from roaster to grinder to brew.  They also pack up their own beans to take home with you (okay for customs).

At Cafe´du Monde at Jackson Square in New Orleans, the coffee comes with a dash of "what's taking you so long to drink a cafe´ au lait of middling quality" from the other waiting tourists.

What a great topic. Few things beat getting lost in a new place and having the chance to chat with some locals over a coffee.

The most atmospheric coffee I've had was after hours of trekking the Batad rice terraces and swimming the icecold waterfalls in Banaue, Philippines. Prepared over a fire and enjoyed while watching the terraces and mountains turning into dark shadows in the night. No electricity and all to be heard was the wild animallife.

I can't recommend the espressos at Bar Centrale in Munich enough, somewhat pricy but a very genuine italian place with charming staff. 

If you are fortunate enough to be passing by Hanoi or Ho Chi Minh, take a break from the busy streets and grab some vietnamese coffee. Check out the coffee street Cafe Thọ or Cafe La Tamia.

Britt Coffee Tour in Costa Rica. second, Juan Valdez Café in Colombia!

Cafe Mirablau in Tibidabo, Barcelona Spain.
