By Gate B74, this is the non‑Starbucks coffee option
Capitol Grounds Coffee sits in Terminal A’s B-gates, right by gate B74, and gives Dulles a locally run counterpoint to the green mermaid. It’s post-security in Concourse B, so you can walk over from A or Z in under 10 minutes if your layover allows. Expect a mid-range price point ($$) and a basic airport setup geared around to-go drinks and quick bites.
The menu centers on espresso drinks, drip coffee, and flavored lattes, typically a dollar or so under what you’d pay in Manhattan but on par with the main IAD Starbucks. Reviews mention breakfast sandwiches and simple cold sandwiches alongside the coffee, plus a small case of muffins, cookies, and grab-and-go snacks. One Reddit regular calls it their “caffeine stop near B74” and rates the coffee slightly better than the generic stands scattered across the terminal.
Rating sits around 3.2 stars, and the complaints are consistent: drink quality swings a bit by barista, and service can feel indifferent during the morning rush between about 6:30–9:00 a.m.. Several Google reviews point out that the baked goods taste pre-packaged rather than baked on-site, so treat the pastry case as pure fuel rather than a treat. If you care about the cup, stick to plain drip or an Americano instead of more elaborate flavored drinks.
Regulars say they walk the extra 3–5 minutes from nearby B-gates when the main Starbucks line is snaking down the concourse. A few mention they choose Capitol Grounds specifically to support a smaller operator instead of another national chain logo. Lines here usually run shorter than the central Starbucks during peak mornings, so you’re more likely to get in and out in under 10 minutes.
Tip: if your flight boards from B70–B79, hit Capitol Grounds first, then use the nearby restrooms and sit near your gate; that sequence burns less of your buffer than backtracking from the central Starbucks.
