There are a few good places to go as a vegan on the Big Island - but as far as I'm concerned - Abundant Life is the best. Delicious vegan Cafe items at a good price. Nice and ample grocery selection. Some really interesting and tasty "Locals Only" items, and best of all - independently owned for a very long time - Support em.
When in Hilo we hit this place almost once a day - sometimes several times a day. Highly Recomended!!
Cons: can't think of any
