They deliver food well within the delivery timing which they mention on the phone. We have tried their malai Chicken and kadai paneer many times and seriously its amazing. Although people do not order salads quite often but I strongly recommend for Mix salad from Zauk. The salad that we received seemed fresh and also looked nutritious.
I have visited Zauk in person only once and my first experience here was good. Quick service and the food served was hot and looked fresh(presentation was good too). As a friendly suggestion, do try out the special veg thali.
It sure is affordable and is perfect for those who want large variety in one place without ordering food items individually and paying heavy expense( the best part is you get a gulab jamnun/rasgulla as sweet desert within the thali price). Zauk takes order even at late hours in the night which is an added advantage.
