I was on a business trip and just happened to book a hotel near the Airport - not knowing that the neighborhood was a Punjabi belt. To that extent, Punjabi Dhaba - happens to be right next to the Airport. I was in Mississauga for around 4 days and I must say that for the first time in my 20 years of being outside of India, I actually had Indian food - in all my meals.
I ended up dividing my visits between Punjabi Dhaba and the Sweet Shop next door - Standard Sweets.
About Punjabi Dhaba - The place is neat and tidy. The utensils are all steel and are very clean. The 2 young guys that I saw front ending the customers - were both sharp and welcoming.
The food is extremely delicious and very very authentic Punjabi style. I tried their buffet selection, Tea, Makki ki roti with Saag etc.....and surely can't complain. The rates are very nominal and very genuine given the quality and quantity of food they serve.They also have a Wi-Fi - so that works out well.
Being from Dallas, where there aren't many true Punjabi restaurants, I savored each and every dish that I tried there.I wish we had a few such joints in Dallas as well.
Do give it a try - if and when you can.
