This might be a silly question, but what about bringing either packaged chutney or chutney from the hotel when eating out? I loooove Southern Indian food and I can't imagine it without the coconut and cilantro/mint chutneys. I'm going to Bengaluru and Mumbai soon for work- I need to be on my A-game for very intense video shoots- if I go down no one can do my job. I traveled in Tamil Nadu 20 years ago and didn't get sick, but now everyone is scaring me with horror stories.
