I have eaten at the Dhaba many times. I have always enjoyed the food and I've tried many items from their menu. The restaurant itself has a nice ambience, quiet, and the service has always been good. Of the Indian restaurants I have been to in Phoenix, this is by far my favorite. I recommend trying something from the chaat menu - these items are complex and flavorful in a way that will delight you if you love that aspect of Indian food.
On weekend nights I would recommend making a reservation as the seating capacity is on the small side.
