I have been to chowka restaurant located in 24th main JP Nagar.
Here is my opinion:
Pros:
You have variety in food.
Veg is tasty but will not score points in Non Veg
Ambience is ok
Cost is less and hence will fit the budget(for treats:))
Cons:
Customer service is worst.
Their response is bad, they dont serve food on time
Their food will be good if the crowd is less, looks like they are not prepared to handle large groups of people.
