I have used tahoora.com to send mithai to ppl all over US. the quality of the product is great and the service is exceptional as well. In one order their was an assortment of mithai and they put the wrong gulaab jamun, although it was not a big deal but when i told them they immediately sent out not just the right gulab jamun but more extra mithai to make up for their error.

btw their pateesa and mango burfi is just amazing.
