Terminal B’s Starbucks is the default caffeine stop
Gate-side in Terminal B at IAH, this Starbucks is the quick fix when you just need a grande Pike or iced latte before a United Express hop. It sits post-security, handy for B’s regional gates, and pricing tracks standard airport Starbucks: expect around $3–$4 for brewed coffee and $5–$7 for espresso drinks. Lines spike in the 6–9 a.m. window when the Houston–Midwest shuttles leave in waves.
Food here is thinner than at many street-side Starbucks, which matches frequent flyer comments about IAH’s outlets overall. You’ll usually see the usual pastry case with breakfast sandwiches, cake pops, and a few protein boxes in the $5–$9 range, but don’t count on hot lunch beyond the standard panini or warmed wrap. If you actually want a sit-down meal in Terminal B, you’re better off walking toward the food court area near gates B76–B84.
Menu board is the national template: Caramel Macchiatos, cold brew, refreshers, plus seasonal drinks when they rotate in, all customizable with extra shots or alt milks for about 60–80 cents. Mobile order may be hit-or-miss depending on the day and barista staffing, but when it’s on, it can cut a 10-person line down to a 3–5 minute wait. Tips from frequent IAH flyers say to keep expectations in line with “basic Starbucks,” not a full breakfast stop.
Watch out for mid-morning stock gaps; it’s common to see popular items like the Bacon Gouda breakfast sandwich and the spinach feta wrap sold out by around 10:00 a.m. during busy bank times. If your flight leaves from a B gate before 7:00 a.m., give yourself at least 15 minutes to clear any line and still walk to the high-number regional gates. Last tip: order your drink size up before a long regional jet leg, since refills aren’t happening once you’re on that 50-seat Embraer.
