I often stop in Porto Rico to get a quick cup of coffee to go, or to get my supply of beans. They have a huge variety of fresh roasted beans, and many at a great value. They charge like $.75 for a cup of coffee if you bring your own mug, which is cheap and environmentally responsible. Their mochaccino usually is bad, and subsequently I dont really trust their espresso drinks. The employees are really lax, which is fine if you are not in a rush, but frustrating if you are. They also stock various coffee mugs, filters, pots, etc.
Pros: Coffee Beans, Variety, Value
Cons: Inattentive Service, Bad Espresso Drinks
