Lovely place with good food. 100% vegan and healthy. Good selection of raw and/or gluten-free items. Friendly helpful staff, sometimes slow and forgetful, but always pleasant.
Clean cool new age atmosphere. The tables are a little close together, but the seating is comfortable and the music softens the sound space. Sometimes there is live music.
Easy to find, plenty of street parking available.
I've tried the dinner and the brunch. Mandala would rate 5 stars except for some food related shortcomings. Raw burrito was full of salty olives - too salty for me, and unexpected in a raw dish. Blue corn pancakes were undercooked, though the flavor was good. (on the bland side, but I prefer that to an oversalted fried ihop style concoction) Also the service could afford to be slightly more attentive.
On the positive side, everything else we ordered was good, though not hugely outstanding. The menu could afford to be slightly more innovative.
Despite some shortcomings, Mandala is by far the best place I've found in the Phoenix area for a healthy vegan meal. It rates among the better vegan restaurants I've been to in the U.S. The prices are reasonable for a nice restaurant and I look forward to my next opportunity to eat at Mandala.
P.S. The spa/apothecary next door is nice and seems to be open even in the evenings for after dinner treatments.
