I spend a lot of time reading thick books and drinking vats of coffee (the life of a professor...). Every now and then I need a bit of pastry or a panini to munch on. Any suggestions for cafes in San Diego? The best have that trifecta of atmoshphere, quality coffee and interesting people. Relatively new to SD, I have discovered, and enjoy, Influx in Golden Hill and Urban Grind in Hillcrest. Other suggestions...?
