I think that number is only if you're living very very comfortably. Personally, on a normal standard of living, I can get by with around $500 USD a month, and that's normal 3 meals a day with internet, phone, apartment (no pool or facilities.) Street food, normal portions are going around $1 to $1.5 USD so it's pretty cheap.

Now of course, you might be able to only afford to go to socialize at bars and restaurants once a month or else you'll blow that budget, but it's possible.
