This is hilariously wrong.
You might say that's completely obvious, but it helps some people to be reminded of it.
You also used the word "only".
Your sentence read as "you can't become rich other than just saving on expenses." Maybe you can see how that is a really weird thing to say.
That said, I'm a big fan of burgers and order them often. Screw what other people think.
Whelp there goes my dreams of hanging with rich people
They had good burgers and chef salad was good as well...
P. J. Clarke's is another one where you could get decent burgers.....
I've noticed that waiters/waitresses seem to treat me worse if I order a beer where I could've ordered wine. Especially when the cuisine is French or centered around steak.
... unless you are taking part in some 'whimsically proletarian' sort of event, or making some sort of 'statement'
