Where can I find cheap vegan restaurants in Makati?

Juju Eats in Pasong Tamo! It's definitely a vegetarian-friendly restaurant although their menu is not entirely vegetarian. You can read reviews here: https://www.happycow.net/reviews/juju-eats-metro-manila-52417

Corner Tree Cafe in Jupiter St! I always go there with my friends and I can say that they offer a good selection of food. And oh, you should try their dumplings! Definitely yummy!
