I am a big fan of Einstein's. Great bagels and coffee. My favorite is the limited edition Winter Blend! They have really great cream cheese flavors to choose from as well as many bagels and sandwich options.
The line can sometimes be long, so make sure you have a few extra minutes if you plan to stop in.
Good tip is to order your sandwich as a "breakfast sandwich" and you are not forced to pay for sides that you might not want.
My favorite is the Lox and Bagel! The new Espresso drinks are great too. I like Mocha.
