We only spent 1 day in San Diego and the very last place we stopped was Local Habit. The service was really friendly and welcoming. The food menu is on the small side but everything looked delicious. They serve meat and cheese but about 2/3 of the menu can be made vegan and is clearly marked. We had an eggplant pizza made vegan with their house-made vegan cheese (tapioca-based). Delicious! In addition to the veg cheese they also brew there own kombucha and sell take-away growlers of it or by the glass. An interesting list of craft beers on tap too. More than the really amazing, yummy pizza, we loved the vibe of this place--trendy but really warm. If you're in the area give it a try!
Cons: small menu
