There are a few reasons I think this place is great. Here they are:
1) the coffee is great. I've had a few drinks from them including Americano and various types of lattes. Delicious.
2) I like the people who work there. Whenever I come in, they are friendly and engaging. The one thing that Starbucks has that many coffee shops I've been to do not is engaging staff. Jimmy does an excellent job of hiring people
3) I like the pictures of people named Jimmy on the walls: Fallon, Kimmel, Page, Hendrix, etc.
4) It is close to where I live (this one may not be as relevant for you).
As an aside, while the good options are not terrific they do have pastries and things. Heck it's not a restaurant it's a coffee shop so treat it accordingly and you'll really like this place too!
