Go to Moti Mahal in Kalupur, one of Ahmedabad's oldest restaurants, which has an extensive non-vegetarian Indian menu, from kebabs to tandoori chicken and Daaba Gosht. It's a must-visit for meat eaters. It's also very cheap.

For those who love sweets, the 160-year-old shop of Girish Chandra Dey & Nakur Chandra Nandy is a must-visit. Here you can have most authentic Bengali sandesh for as little as Rs 10. You eat one piece and guaranteed you will want more. For people with more modern tastes, they also sell sandesh flavoured with chocolate, strawberry, blackcurrant, and a strawberry chocolate fusion.

Indulge in some street food
Calcutta is famous for its amazing food: tandoori, continental, Indian, all of it, but its speciality is the street food: Puchka, the Bengali version of Bombay's pani puri and Delhi's gol gappa, is a fried hollow cupcake filled with potato, grams, and spicy tamarind water. You can't miss it when in Calcutta. You have many variations of it. Puchka with dahi (yoghurt), puchka with water and puchka with sweet water. What's common to all is that they have a basic potato filling. Then there are the chaats: the jhalmuri, the hing kachori and sweets. Another street-food favourite is the biryani (rice with meat and spices), which is completely different from its other cousins, the Hyderabadi and Lucknowi biryanis. If you are a food freak, and like biryani, you cannot afford to miss the Calcutta biryani. What makes it unique is that it has potatoes as well as meat. It caters to various palettes, so to say, ranging from the extremely rich, oily ones, to the less spicy ones for the health-conscious people. Deep Dasgupta
Check out the night clubs
This is for the young at heart. There are plenty of nightclubs - Tantra, Roxy, Sheesha. Unlike other cities where everything shuts down at 11pm or 12 midnight, Calcutta is a place where you can actually get out of a night club and go straight to breakfast. You can have a really nice night out and then head to a place like Flurys in the morning. The underground music scene in Calcutta is perhaps the best in the country. The bands from Calcutta are loved throughout the country, and are must-haves in music concerts anywhere. Especially Bengali bands. So mark down a visit to Someplace Else. Every night of the week live bands perform there. And they are really, really good. Anyone who is in to rock music, goes to Someplace Else. Bengali bands usually play in auditoriums. So if you can't catch them at a concert, there is always Someplace Else. Deep Dasgupta
Eat traditional sweets
Sink your teeth into a roshogolla or a sandesh from KC Das. Made out of milk solids - the roshogolla in a sugar syrup, the sandesh its dry counterpart - they can be very, very sweet.
One of Kolkata's oldest markets is ironically called New Market. Do check it out. It is very close to Park Street, and you can buy all sorts of stuff, including leather goods. While in New Market, do try the chaat (spicy snacks) and puchkas (hollow deep-fried balls with spicy tamarind water) outside, and ask someone for directions to Badshaah which makes rolls (meat/egg/veggies in wraps) to die for!

Tea in mud pots
Drink lots of fluid. Kolkata is humid at the best of times and a day out can leave one dehydrated. Recharge by drinking lots of water. Try the tea, too, especially when it's sold in small earthenware pots. The tea is boiled and so is safe, and the pots are broken after use and so are hygienic - and eco-friendly.
