To be fair, the drink was actually a quadruple shot, because each pulled shot from Bella's machine yields a double. Still, $8 seemed high, especially because my server neglected to tell me how the machine was set up.
So I did some comparison work.
Frasca Food & Wine, 1738 Pearl Street in Boulder: $5 Colt & Gray, 1553 Platte Street: $6 Masterpiece Delicatessen, 1575 Central Street: $5.50 Pizzeria Basta, 3601 Arapahoe Avenue in Boulder: $6
I checked these places because they're restaurants of a similar price point or use high-quality roasts -- although Bella Bistro uses an imported roast, while several of the spots above source locally.
Am I crazy for being a little annoyed?
How much would you pay for a quad shot of espresso? Especially after you asked for a double?
