Did you go to La Colombe yet? It's not just a great local chain, it's probably at the forefront of coffee nationally. The entire place is based out of Philly, but the owner is recognized worldwide. He has his own show, Dangerous Grounds, on the travel channel, and is generally consider a modern expert on coffee. La Colombe is probably the greatest third wave coffee producer in the USA. La Colombe has a cafe near you at 19th and Walnut, but to experience the best you need to check out their place in Fishtown, and maybe sample some of their house distilled rum.
You want to go back to Cali right now, but it's only because you don't have a full appreciation for the East Coast yet. You'll shortly realize that the East Coast is, in reality, better than california in every way. More to do, more to see, more to experience, more to eat, more to drink, and more to life than the boring west coast. You can experience the great aspects of the east and the west here. You can experience the birth of our nation and the best of our nation in one spot. If you have any sense you'll never want to leave.
