Coffee here gets the job done - very strong, but also sweet.
The reason why this place gets 3 stars in my book is because it is super overpriced! I don't think a regular size should cost ~$6 (or ~$7-8 for a large) after tax. There are really good coffee out there that doesn't cost that much.
If you need your coffee fix and would rather go here than Starbucks, try the flavored lattes. I personally like my coffee with some sort of sweetener, and I think the lattes are a good balance of coffee strength and sweetness.
