As a 4 year Madison resident, I've been to every Indian restaurant in the area. Dhaba was surprisingly excellent. The atmosphere was very clean, quiet, and professional. We had the veg biryani, naan, and vegetable mango curry. The food was awesome; not too spicy, flavorful, and they were in decent portion. I would have easily had to spend twice as much for the same dish at a place like Swagat or Maharani. Don't forget this is is Bistro as you may not get the most cordial waiting staff!
