Looking for a restaurant to have a leisurely lunch on Thursday. South of 14th preferred. My dining companion is vegetarian, so something that can please a veggie is required. I don't want to be rushed, as she's helping me with a project I'm working on, and we're planning to chat for a while -- I'd like to have room to take notes if necessary (so places with tiny, cramped tables would best be avoided). Casual dress, but it doesn't have to be dirt-cheap (~$30 a head is fine -- we won't be drinking, though less is alright too).
