There's a very specific meaning to price rangers of restaurants, I always use Yelp $ sign ratings as an example; they categorize every place into 4 price ranges from $ to $$$$. Generally, the breakdown is as follows:

$ - counter/fast-food/food truck/sketchy

$$ - regular

$$$ - regular, but very small servings and artfully arranged

$$$$ - fancy

The key is to avoid the $$$ places ;)
