Sushi - http://www.yelp.com/biz/i-love-sushi-henderson (Its a BARGE tradition and I visited recently, I am thinking of dragging Barry H. out there in February)
Comfort food/Diner - http://www.tripadvisor.com/Restaurant_Review-g45963-d507650-Reviews-Bay_City_Diner-Las_Vegas_Nevada.html
Italian - http://www.lasvegasrestaurants.com/restaurant.cfm/restaurant/1155/NoveItaliano (the site claims $$$ but i thought it was a little higher, they have a $45 fixed price option)

I have heard great things about the italian at the M (I think Andy H reiterated it the other day but he's the third person I heard this from).
