Coffee in the United States is served by three kinds of places: national chains with drive-thrus and mobile ordering, independent neighborhood cafes that double as a workspace or a meeting spot, and specialty shops that roast their own beans or buy single-origin lots and brew them by pour-over, espresso or cold brew. Most open between 6 and 7 a.m. on weekdays, slightly later on weekends, and the busiest hour is the commute rush before 9. A drip coffee runs a few dollars, espresso drinks and specialty pours more, and tipping a dollar or a percentage on the card reader is customary but not required. Nearly every cafe offers free Wi-Fi, though some limit laptop seating at peak times or on weekends, and outlets are often the scarce resource.

Hours are published for 7 days a week. On most of those days it is open 8 am–4:55 pm. Hours in the United States do change around federal holidays and long weekends, so a quick call before a special trip is sensible. You can reach Principles GI Coffee House at (347) 218-4290; calling is usually the quickest way to ask about availability, prices or directions. More information is available on its website, principlesbk.nyc.

Brooklyn is in New York, in the Northeast, where four distinct seasons shape local life: hot humid summers, snowy winters that can close businesses for a day, and a dense pattern of towns where walking, transit and street parking all matter. Getting around Brooklyn is easiest by car; street parking is metered in busy downtown areas, and most suburban businesses have their own lot. Ride-share apps such as Uber and Lyft operate across New York's larger cities, and public transit varies from extensive to minimal.
