I hope the owner will take this as a good gesture to help them improve, and I'm not complaining.
It looks like a family run Restaurant which definitely needs improvement on the food quality, Kebabs were little over cooked, had grilled pink tomatoes which should of Ben Red.
The owner was very friendly, and I think adding a little of Persian culture to their service would go a long way such as Sabzi (Parsley) and onion plus a little feta cheese, showing and presenting the culture it's respecting who we are and the customers.
Overall they did good.
