Your question is useless. There are tens of thousands of restaurants in the area.
What types of food do you like to eat?
What neighborhood or suburb?
What style of restaurant (high-end, fast casual, counter service, etc.)
How much do you want to pay? Not all great restaurants are expensive.
As Kyle said, read articles and reviews, although don't take these silly lists seriously like "the 100 best restaurants". (They are invariably written by lazy reporters or junior staffers just to fill space.)
Use reviews written by REAL people. I used to write hundreds of Yelp reviews, and they were impeccably correct - if I must say so myself.
