Correct me if wrong: as I understand warungs are small road-side eateries. I'm from India and here the street food is extremely cheap and often extremely yummy. But it can also cause illness because of unhygienic conditions of preparation and use of adulterated ingredients. Do warungs involve the same risk? Don't mean to be insensitive to the warung food lovers here -- just relating to what I know and checking if comparisons are apt.
