I usually will rate Coffee places with the following 3 categories. Service, Cleaningness and Product if that's a local coffee shop. This Starbucks is the closest from my place and is conveniently located right at the Jones Exit of 215.
Service 3.5 / 5: Good service usually at this Starbucks. Not the most friendliest I ever experienced in a Starbucks but not that bad. The Drive-In is usually busy so park your car and get your *** in the Bucks. You'll save some time actually if you're in hurry.
Cleaningness 3.5 / 5 : It is usually clean even if sometimes, you find some tables that aren't cleaned out really well. It is not dirty, you might have to clean your table sometimes.
It is really conveniently located but it is sometimes a little bit dark inside even when the weather outside is sunny. Not the best to work for couple hours but good enough to grab a drink on the go.
