Then there are a few other important Ganpatis worth visiting: Akhil Mandai, Dagdusheth, Bhausaheb Rangari, Jilbya Maruti, and Babu Genu Mandal.
For breakfast and lunch
Vaidya Upahar Gruha, Prabha Vishranti Gruha, Poona Guest House, Shri Krishna Bhuvan, Shripad Idli Centre, Bedekar Misal, Annapurna Snacks, and Supreme Sandwich are some good options for breakfast.
For lunch, Durvankur is a great choice.
Kaka Halwai and Chitale are the go to sweet shops.
You should also try Sujata Mastani, Kawre Cold Drink House, Lassi Ghar, Shirdi Ice Cream, and Devyani Ice Cream.
For shopping, especially for women, you'll find literally everything at Tulshibaug.
And if you find the time, do visit Talyatla Ganpati at Sarasbaug, Shaniwarwada and the Parvati Temple.
Use the metro wherever possible. Do not bring a four wheeler at any cost. And try your luck with 2 wheeler parking. Get down at PMC metro if u are using Line 2 and at Kasba if u are using Line 1.
The real fun is in walking around and exploring the different mandals so avoid chappals, slippers, and sandals. Wear proper shoes, and carry water.
