Coffee Bar address is on Bryant St. But it is really on the NE corner of Mariposa and Florida. You will see a Starbucks before you will find Coffee Bar. But resist. It is well worth it.
It is a 2 level place. Ground level has an outdoor patio (this is in Potrero Hill area and the patio faces south – there is sun there a lot) and the service area. A 1/2 level up is a loft like table and couch area.
It is well designed and very naturally bright. You just feel good there before even the coffee.
The food is light and healthy, the coffee is very good, the atmosphere is great. This place is hard to beat and well worth it to hang around.
BTW – they have great teas too if you are not a coffee drinker.
