Looks so tasty I want to fly down and eat it :) I had food ready for my dinner but feel I need to buy some fried fish to get some tasty morsels into me after seeing your photos :D
Speaking of roadside diners, in India too we love them. As long as they are clean to the extent possible (i.e. no cockroaches, constant wiping of tables and floor, etc.) I am ok to eat there. Typically I find the roadside stalls and hawkers can give very tasty food, and the food is fresh - thanks to the constant stream of customers they get. I always check what everyone is ordering and only order those as those items will not be stale in most cases. In India since most cooking requires spices as well as high heat I feel pretty comfortable wrt not getting bad food. Of course having eaten out all my life my stomack is used to the spices too :)
Thanks for great post, now I need to go and order some fried Rohu.
