Fumari is a great place and an alternative to the coffeehouse culture. You can rent a hookah (a communal water-chilled tobacco pipe) by the house with some of Fumari's flavored tobaccos. Some of the better ones are Double Apple, Mango, and Rose Flower. They are located in the heart of the Gaslamp Quarter so they are walkable from Horton Plaza and they have comfortable chairs to lounge on. It's a great place to kick back and unwind after work or to study.
