Yes, this place can get busy and parking can be a nightmare so it's not likely to be an every day stop but it is a WONDERFUL special treat. The old train depot is just such a cool building and exploring it a bit is what makes coming here fun and worth doing. There is also ample seating indoors (upstairs has seating, even outdoor seating on the balconies) and especially outdoors - which is where I recommend you sit and sip your tea and enjoy your goodies.
I've never had their coffee but they have an extensive tea menu. They'll make any of the teas hot or cold and they have almond or coconut milk as non-dairy options for your coffee and tea drinks. My favorite on a hot day is the coconut oolong with coconut milk - a very light, refreshing, and tasty drink! They also have a great menu for a light lunch and plenty of baked goods to choose from, including gluten-free selections. The pumpkin pecan muffin was delicious.
I love this spot, it's a great place to go for a special treat when you have some time (it's not a place to pop in for a quick coffee or tea!) or to take out-of-towners (or go to if you are an out-of-towner!). I like to go here with my girlfriend after we hike Torrey Pines and are heading back up the coast to Carlsbad for a refreshing tree and a goodie. Also a great spot for cyclists along the coast to refuel!
I recommend going, at least once!
