Been here a couple of times for breakfast on Sunday after a long bike ride with friends. Always bustling with activity, lots of which are ASU students.
I recommend going on a day that's nice enough to sit outside, the patio is great for people watching! It is a self-serve cafe so much more casual in nature than other breakfast eateries but the food is awesome for the price you pay. 3 huge, fluffy, perfect pancakes with mix-ins for $6.50. If you love pancakes as much as I do, these are some of the best.
If you're in the 'hood and can deal with the early closing hours, I definitely recommend this place amongst the many 'drab' eateries on Mill Ave.
