Do you think crowded restaurant means good food?!

Good food does not necessarily mean good health, but that is a question for another day as the explanation for that is long and rather drawn out. Usually restaurant's are crowded for the following reasons; The food tastes really good (not necessarily health), service is quick, the restaurant is part of a large chain brand of restaurants, a popular item is on special, or the food is really cheap. Other reasons can cause restaurants to be crowded but those are the main reasons.

If the restaurant is newly opened in the area then i dont give the crowd factor much notice. Let the "new " wear off and in 18 to 24 months if it's still crowded then it obviosly has SOME draw to it. . .may be the food or it may have 16 big screens , a fantastic bar selection, and/or sexy servers. . .

I was a sexy server in a really fun sports bar . . Many years ago. .Lol

it means almost all the food stuff gets finished everyday, they do not have to refrigerate stuffs into refrigerator to be served to the customers next day. So you get fresh things and naturally fresh things are good for health

Most often a crowded restaurant is a good sign but it is also a sign that you will have to wait for your dinner.

Normally it's either cheap or family friendly...
Or just 'good food' that's over rated.

Experience.

Not necessarily. Best way to know is count the number of Asians, the more the better. They know good food.

Crowded resturaunt probably means a really good price for meals. But its bad to wait for such a long period of time.

i would not say it necessary makes it healthy but the food probably taste nice

crowded restaurant means cheap food.

No.
McDonalds is always full but it isn't very good.

It either means good food, fame or cheap prices.
