<human>: My best friend is Chinese and he eats very loudly. When we get pho or other kind of noodles, he'll slurp the soup and go "ahhh" after he swallows it.  He'll also chew with his mouth open.  I've been to restaurants with him and people will turn around to look at us because they can hear him eating. It's pretty fucking embarrassing. 

We've been friends for 10 years now. He's kind of a sensitive guy and I know it's going to piss him off if I tell him he eats too loudly. Plus I think it's a Chinese cultural thing to eat loudly and slurp soup like that. Should I tell him he's embarrassing himself by eating too loudly? And if so, what's the best way to do it?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My friend eats really loudly and I'm not sure if I should tell him he's making himself look bad. Plus, it makes me feel weird eating with him.
