Bikaner
Bikaner's old city hides some of the finest merchant havelis in Rajasthan — elaborate sandstone mansions with five-storey facades carved as intricately as lacework. The Rampuria havelis on the main market road are the most spectacular, and the surrounding bazaars sell Bikaner's famous bhujia snacks, silver jewellery, and Rajasthani textiles in a setting that has barely changed in a century.
Try the Bikaneri bhujia and rasgulla from the original shops on Kote Gate road — the local brands are far superior to what you find in airports and supermarkets.
