I'm in love with Starbucks and their very special brand of overcommercialized caffeinated goodness. When they provide their little paper cups of love in a drive-thru, I am sooo there.
The Eastchase Starbucks is arguably the busiest and the best of the four Montgomery locations. The service can be kind of hit and miss - it's usually great, but there are some mornings that they can run pretty slow. Who knows if that's the barista's fault or some customer who doesn't know what venti means, though. ;)
On the few occasions where I've had slow service or a mismade drink, this Starbucks' employees have always been gracious and accommodating, remaking drinks or offering free drinks to compensate.
They've earned my continued repeat business with their excellent product and customer service.
