Chinese food in Vegas is stupid. Especially if you're from Vancouver where Asian cuisine is abundant, competitive, fresh and delicious.
In Vegas I had $33 for a tiny ass bowl of BBQ Duck on rice, which was ok, but definitely not worth $33... I could almost get a whole damn roast duck in Richmond for that price lol. Never again.
$20 (USD) for stir-fry?! Not sure where you eat stir-fry in Vancouver but no where I go charges me $26 a plate. It better have Lobster in it.
Japanese food is also ridiculous, my friends dropped $400 for 2 people and they had some non-inspiring food that is what you could find for 1/4 of the price in Van.
Personally Vegas is pretty much buffet and liquid diet.
When I have extra time I visit Maggiano's for Italian and PRIME steakhouse in Bellagio, Estiatorio Milos in Cosmo. Those are some nice spots to hit if you aren't down for stuffing yourself.
