I like coffee, especially cappuccinos, so that is mostly what I evaluate. This page primarily has recommendations for small and independent coffeeshops; if instead you want inexpensive or mass-market coffee, it's not hard to find. For pedants, this page additionally contains recommendations for non-coffee items.

There are many medium-to-large-ish chains, with varying levels of consistency and quality, for example La Colombe or Bluestone Lane. The line between "chain" and "small and independent but with multiple locations" is nebulous; I make no promises of semantic consistency.

Also, thanks to the various members of my coffee committee (in alphabetical order), Albert, Deepti, Panda, Paroma, Pratiksha, Rachee, Sagar, Shoumik, Shriram, and Vipul sending in their suggestions! Please get in touch if you have a scouting report to share.

• Ogawa Coffee is the best Boston cappuccino I've had thus far (as an added bonus, the baristas make elaborate latte art designs). George Howell Coffee is also great: the flavor is well balanced, and the baristas pour excellently.
• Bakey is a bakery + coffee shop. They have great pastries, especially babka ("Ovens Always On"), but their coffee is a first-class part of the shop (their roaster is Seattle's Caffe Umbria).
• Barismo and Broadsheet are good options in Cambridge. Curio in East Cambridge has not just good coffee, but also excellent liege-style waffles. Elmendorf nearby is a good bakery and baking materials supply shop (but Curio's coffee is better).
• Area Four and Vester are good options near the Stata Center.
• Pavement is a good option if you're in Back Bay (there is now also a Pavement location in Harvard Square, in the student center). Flat Black is operated by Australians and thus has flat whites (the one near Downtown did not survive the pandemic; the remaining cafe is close to the Red Line's Mattapan Trolley extension near Ashmont).

• Highwire, CoRo, and Artis are good options if you've just had lunch at Vik's (or are otherwise near the Fourth Street area).
• Guerilla Cafe uses Artis beans in a more easily accessible near-downtown location.
• The old favorite near Soda Hall, Nefeli Cafe, is now closed, as has Brewed Awakening. Instead, Mind is probably the best option.
• Philz is good at non-espresso coffee. There are several locations, including in the South Bay. Their Shattuck Ave. location is now closed. People are sad about this.
• Asha is, as far as I'm concerned, the One True Boba Place.
• Scouting report: Vipul recommends Timeless in Oakland and Ain't Normal in Rockridge.

• Ritual Coffee Roasters is probably my favorite cappuccino in San Francisco.
• Dandelion Chocolate may have chocolate in its name, but they serve great coffee! I recommend the Mission Hot Chocolate or Mission Mocha (they use Four Barrel beans).
• At SFO airport, T1 has a Ritual Coffee and T2 has an Equator.
• Scouting report: The SF coffee scene has seen a lot of evolution since the above two recs (which are still good). Rachee likes The Mill, which serves Four Barrel beans. Vipul likes Golden Goat, in SoMa.

• Cafe Venetia is my favorite in Palo Alto, and Verve is also good. Manresa Bread is primarily a bakery, but serves coffee with Verve beans. On the Cal. Ave. side, Backyard Brew is good (thanks to Pratiksha for the recommendation!). Boichik has great bagels which rival New York's. Within Stanford, Coupa Cafe is close to Gates Hall and decent.
• Coffeebar and Saint Frank, in nearby Menlo Park, are also great options. Saint Frank has locations in SF as well.
• Backhaus, in San Mateo, has good bread and bakery items in addition to coffee.
• Red Rock Coffee is my favorite in Mountain View. Midwife and Baker, a bakery that supplies many Bay Area cafes, also has good coffee (note May 2024: coffee service at Midwife and Baker has been temporarily suspended - they are working on getting it back). Voyager is a good (though often crowded) option in Cupertino.
• Devout is a decent option in Fremont.

• In Greenwich Village there is La Cabra, a cafe with Danish origins. There is also 787 Coffee (787 has multiple locations, including in lower Manhattan and midtown) and Third Rail.
• Near Grand Central, Black Fox Coffee is quite good. They also have locations in lower Manhattan, Hudson Yards, and near Penn Station (this is probably the best coffee near Penn Station).
• Near Madison Square Park, Stumptown is a good option. There is also a Black Seed Bagels around the corner.
• On the Upper West Side, there is Black Press Coffee.
• Caffe Panna has good affogato, but don't get their coffee.
• In Brooklyn (Dumbo), Butler is good. In Williamsburg, Lion's Milk is good.
• At JFK airport, the TWA Hotel at Terminal 5 has an Intelligentsia, which is the best (pre-security) coffee at the airport (the primary competition is various Dunkin Donuts throughout the airport). The hotel was once an airport terminal for TWA airlines, and is architecturally interesting.

• Espresso Vivace has a founder who apparently invented latte art. This has been my first stop after multiple red eye flights.
• I'm writing this from Floret, in SeaTac Airport near the A gates, which has Stumptown beans and a La Marzocco espresso machine and surprisingly good coffee for an airport. It's also a great option for vegetarian food at the airport.
• In Bellevue, Cafe Cesura and Third Culture Coffee are good options. Third Culture additionally has Indian-inspired options like filter coffee and chai.
• In Renton, Boon Boona Coffee is the best option. The cappuccino is not great; I recommend a cafe latte instead.
• Five Stones in Redmond will make you a cappuccino freddo, which is not something you usually see.
• Scouting reports: Panda reports that Ada's Discovery Cafe (also in Capitol Hill) and Santo (a bit north of the U-District) are good. Rachee recommends Victrola, with locations in Capitol Hill, downtown, and on Pike St.

• Bolt Coffee inside the RISD Museum is really nice and near Brown University (thanks to Theo for taking me!). Ceremony is also good, though it is primarily tea-focused. Nearby, Coffee Exchange on Wickenden St. is similarly good and has an extensive selection of beans.
• Small Point Cafe is a good option downtown. There are also two other Bolt locations in downtown Providence.
• Seven Stars Bakery has George Howell Coffee and also good pastries, bread, etc.

• In Redding, Theory is a good option.
• In Crescent City (near the north border of Redwoods National Park), Paragon is good.

• In UCLA/Westwood, Espresso Profeta is a good option. Saffron and Rose is a good ice cream place nearby.
• All the way out in Fullerton, Dripp is good, but expensive.
• In the San Diego area, Lofty is a good option with locations in Carlsbad, Encinitas, La Costa, Solana Beach, and San Diego itself. Bird Rock is another good option closer to San Diego. Also in the area is Prager Brothers bakery.

Hawai'i (the state) has a coffee growing industry, thanks to the volcanoes. Most of the growing happens on Hawai'i (the island), in particular Kona coffee. It's certainly possible to get mass-market coffee (Starbucks, Lavazza, etc) here, but it's worth sampling the local product.

O'ahu

• The best coffee I had in Honolulu was at Honolulu Coffee, with locations including the lobbies of the Prince Waikiki and Moana Surfrider hotels. They roast Kona coffee.
• Other places near Waikiki, though promising, were too crowded to evaluate properly.

Hawai'i ("Big Island")

• HiCO, with locations in Kona and Captain Cook, serves Hawai'i (state)-grown coffee. They serve coffee from a rotating series of Hawaiian roasters. This was my favorite cappuccino on the island (but not by much).
• Kona Coffee and Tea roasts and sells Kona coffee. They also sell Hawaii-grown natural wine.
• Scouting report: Close to South Point, across from the famous Punalu'u Bake Shop, is Ka Lae Coffee, which is a promising place for Ka'u coffee, another big coffee growing region on the island.

Kaua'i

• Java Kai, in Kapa'a, is the best cappuccino on the island (but I prefer their cafe latte). You might also be interested in the Kaua'i Coffee Plantation, but they serve only drip coffee.

I will leave you in the hands of the Atlanta Coffee Shops project.
