I wish I'd known about Terra earlier. Located north of Naples in Caserta, it was a great way to finish off a day trip to the Caserta palace.
We arrived early by local standards at 7:45 pm, and were able to sit down but not order until after 8. We had the place to ourselves until closer to 10pm, when the restaurant became much livelier. Our server was friendly, spoke English well enough to meet our mediocre Italian halfway, and was happy to take the menu back for the chef to star the items that were vegan. (probably at least half of them were) For vegans in this area, eating out is generally easy, until you want a second course / some protein, so it was nice to find an exclusively veg place that offers vegan secondi.
The starters were delicious - we had a trio of unusual bruschetta (I think one was pumpkin, another zucchini, and a third traditional) and a phenomenal cone full of tempura vegetables. For primi we enjoyed white beans and a risotto - good, but probably the least standout of the items we tasted. This was a little surprising in retrospect, since everything else was delicious and it's generally very easy to find a variety of traditional primi that are vegan or easily veganizable in this area. For our secondi we both ordered the seitan alla Venezie, which means with caramelized onions, and we both loved it. The selection of natural (organic, probably?) beers was interesting as well and the German one we tried was very good.
Ambience was nice. The restaurant itself is quiet and tucked away a bit on side streets - we were lucky to snag a spot near a busier square and walked 1/4-1/2 mile or so. At a busier time it might be advisable to park in a lot, since the city center area is traffic-limited. Disabled people might have a trickier time getting to the restaurant, unless there's a way legally to park closer.

Cons: hard to park very close
