I must admit that I do kind of miss the Einsteins Bagels that used to be here. One complaint I have about Starbucks is that it's pretty hard to make a lunch out of it. The parking lot (shared with Bertuccis and a couple of little places in that location) is a decent size, so parking generally isn't an issue, though at peak times you might need to park across the street. It's very convenient to the many buses that run down the street from Watertown Square, so a popular place in the morning as people head to the Express Bus to downtown. It's hard to review Starbucks since generally it's the same pretty much everywhere you go. No surprises here -- all the usual stuff. The staff is pretty accomodating (recently the music was very loud, and they were nice about turning it down).
