According to me & I am sure many Mumbaikars will vouch for it, the best street food can be found in localities dominated by Gujrathis. The lane opposite Matunga Central station offers Pani Puri, Ragda Pattice, Dabeli, Sandwhich, Bhel, Sev Puri, Kerala Wafers, etc all within a distance of 20-25 feet. Pani Puri comes at Rs. 10. Dabeli costs Rs.6. Have eaten there since childhood & never had any gatric accidents. Go there & eat out pocket out.
