NAPIZZA- San Diego, CA  (1702 India Street, San Diego, CA ). This organic pizza restaurant offers pizza by the slice and has two GF options daily (at least 1 is vegetarian). The crust is very thin and crispy. I ordered a slice of the sausage and broccoli and it was delicious. Size of slice was about 4 1/2 inches square for $4.00. They offer custom salads and whole pies as well. There is seating at their lovely sidewalk patio area. They have various beers and sanrgia and are interested in carrying GF beer options in the future. They do offer to deliver within 1.5 miles of their location. Can't wait to go back!
