Though quite popular I have had one bad experience here after another. Service bordered from curt to rude with the barrista spending five minutes arguing with her boyfriend on the phone instead of serving the counter. This is a coffee bar only, seating is outside on the sidewalk or at a few tables in the lobby area. You get your own sugar and stir stick. They have a couple of teas, but mostly custom coffees. The family has opened another Kaldi in Glendale in the same format, but the service was much faster.
We have been taking friends to Tea Rose for years. The staff is accurate and friendly, greeting us by name when we arrive. The service is the slow side of leasurely, you do not feel rushed. They are across the street from the free (90 min) parking garage in Old Town Pasadena, so the location is convenient. Their teas and presentation are very good in a more casual atmosphere than at Chado. The restaruant is at the front of a popular flower shop. Look forward to lots of interesting things to browse as you talk with friends. Don't take your contractor buddies there like I tried. One wouldn't even go in the door!
