I have not seen calorie counts, but I don’t question what you say about calories. For example, the highest calorie menu item at Tender Greens–by a pretty wide margin–is their “Happy Vegan” salad. https://www.tendergreens.com/files/Nutritional%20Card_48384.pdf
That said, I think that the food at Cafe Gratitude is very healthy. One just has to remember that it’s not diet food; moderation is still essential.
