Bosa is a nice little place. Its not extravagant, but it has good drinks and great donuts.
The drive-through intercom is the worst. As if I didn't already dislike hearing my own voice, it comes right back to you in duplicate with feedback. The staff is friendly and service consistent. The speed at the drive thru is moderate, depending on how busy they are.
The fact that I can get a Thai tea boba at a drive-through is fantastic. Not the best one I've had, but it does the job. The donuts are always fresh. My personal favorite is the Boston Cream. I have also gotten a few sandwiches at this location. The turkey is just cheapie lunch meat, so I want impressed. The bacon, egg & cheese is great on either a bagel or croissant. Neither are anything to write home about, but makes for a quick and sturdy breakfast.
