As of March 2010 the set meal of the day costs 5.000 pesos. The food overall was good. This may sound strange, but even though this is a vegetarian restaurant, there weren't enough veggies on the plate. There were protein and starch items, but I like to have a variety of other non-starchy veggies such as carrots, broccoli, celery, etc. I only ate there one time, so it may be better on your visit. The set meal is a good deal, and comes with a juice drink or an infusion of some sort. They are open for lunch only, and I would arrive no later than 1:00 p.m. It's right in the middle of the historic part of town, so easy access for the typical tourist.
Cons: Lack of non-starchy veggies
