Karaikal is a small town which hasn't got anything to interest a normal tourist. It is surrounded by the Cauvery delta region, Tanjore, Tiruvarur, Kumbakonam, which were the hub of the ancient Chola kingdom, which are spotted with a number of temples which are rich in the Chola architecture. Mainly pilgrims and people with an interest in history and architecture will be interested.
Karaikal has got its own brand of halwas(sweet), though not as famous as the Trinelveli halwa, there are quite a few shops in the Barathiyar road, near the Tirunallar junction, where you can buy these halwas as well as sweets like gulab jamuun.
Muthupillai Bakery actually has a restaurant within the shop, the Milky Way Ice Cream shop. The Manikandan mess in the Daweed pillai street is a vegetarian mess where you can get quality authentic south indian food. Karaikal "Rasi Alwa Kadai" is a very famous alway shop. Dont miss the taste. Reputed stores like "Nagore Alwa Kadai" specialises in Alwa, Butter kova, Milk kova, cotton-seed alwa, apart from the almond variant and Dumroot alwa. And then there are the unique, succulent gulab jamuns. The intricacies of flavours can satiate any taste bud.
The JP Sarbath shop on Church street (near Muthupillai's restaurant) is the place where you can get fresh fruit juices and sarbads at relatively cheaper cost. The Seven Eleven juice shop in the Church street, also called by "juice kadai" by the native people, is a good hang out. In Karaikal, liquor is cheaper than the adjoining Tamilnadu. There are quite a few decent bars in Karaikal.
