First time visitor to Mexico. I'll be in Mexico City and Cuernavaca next month and I'm looking for some tips. In Mexico City I'm staying in the zona rosa. I'd like to eat some great Mexican food in both places that won't break the bank as I'm on somewhat of a budget. I could splurge out once or twice(keeping it under $100 U.S.) I'm fine with eating local, off the tourist trail but I can't speak Spanish so this may be an issue.
