After a long, exhausting day, the place to head is a cool air conditioned mall with some great restaurants! I recommend Cream Center, which is a completely vegetarian restaurant that serves a great range of dishes from different cuisines (Mexican, Indian and Italian!). I love the nachos and panna cotta, and they also have a mean panneer chilli sizzler! The place is a bit pricey, with a meal for one person ranging between 400-800 rupees, but it is still worth it. The mall also has a decent food court for those on a more limited budget, and one can still enjoy the comforts of a mall.
