Is it rude to make a remark about how expensive a restaurant is when sitting down to eat with your friends?

It depends; if it's fine dining, you expect to pay more without making comments.

I walked out of a restaurant once where the least expensive choice was over $50.

If you have agreed to join friends, you should ask about the price of the food beforehand, if it will be an issue.

This comes down to personal choice and what feels right for the individual. It would not be uncommon for people to comment on the pricing at a restaurant if this was more than they expected. Also, keep in mind that what one person considers expensive will not necessarily be the same for someone else.

No, if you think it's expensive then have your meal and then excuse your self to wash your hands. When no one is looking, just sneak out the back and stick your friends with the bill. If they call you about it, just say you thought they were buying because you would never go somewhere so expensive.

Yes it is rude. You will embarrass your friends. If you consider the restaurant to be too expensive, why did you go in to it? If your friends selected it, then it would be disrespectful to complain.

if one person has chosen the restaurant and u re making a comment that the restaurant is expensive that person might think u re making a jab at her/him. so better refrain from commenting. if u were a company and just walked into the first restaurant u saw and u make such a comment after looking at the menu - that is ok, nobody gets hurt feeling

Yes. It suggests you are putting a price on friendship and you come off looking cheap. You can order frugally (if you must) on the basis of being on a special diet, and resist dividing the bill equally.

No, I would probably agree too or persuade you that it's worth it. It honestly depends on your group of friends but generally it's not rude

I wouldn't think so, especially since they're your friends you should be able to say whatever you want.
