I have visited in chennai and delhi branches(most of them) and was happy (with our family family trips as well). Was amazed to see the same in delhis three branches as well. customer service has been a key differentiator amoth their peers along with the taste they have across all varieies of south indian food.
Pros:
Nice food.
Noharm to kids at any time.
tastes same.
Fantastic/excellent service.
Highlights
Irrespective of location the taste and service never changes.
Nice to go with kids and have variety and no worries on food quality
the service has to be appreciated except one or two occations out of our more than 50+ visits
Opens early in the morning and there nearing midnight
Price not too high. above average (aspecially comparing delhi price)
Located in comfortable/prominent places
Value for money (check youself atleast once to confirm the same)
Customer service (as mentioned earlier) is excellent and worh mentioning again
you could get icecream and south indian snacks (sweets etc) as well
