Estimate the number of restaurants in Bengaluru, India.

To tackle this guesstimate question, start by breaking down the problem into smaller, manageable components. Consider the population of Bengaluru and the average number of people per household to estimate the total number of households. Next, think about the dining habits of the residents—how often they eat out and the proportion of households that might dine out regularly. Use these insights to approximate the number of restaurants per capita, factoring in different types of dining establishments (e.g., fast food, casual dining, fine dining). Finally, validate your assumptions with any available data or trends specific to Bengaluru's food scene to refine your estimate.
