Freesoulcaffee is one of my favorite local spot. It sits just off of the Old Town Tustin area and offers nice indoor and covered outdoor seating. The owner and the employees are all very friendly -- and the food is really good.
They offer a variety of baked goods, soups, salads and sandwich/panini choices. The coffee, tea and hot beverages are really amazing -- try the spanish hot chocolate for nice treat. Soups are all made fresh and come with a couple of chunks of nice bread. Portions are generous.
The first time I went, I made the mistake of ordering a bowl of soup and a full sandwich -- the soup was plenty for lunch. I ended up taking the sandwich (which comes with a small side salad) home for dinner.
Have not yet been for any breakfast items - but I plan to be back.
