Del Frisco's is a remarkably good restaurant in a city full of great places to eat. Not pretentious, just delicious and very pleasant. Our server was top-notch and two managers stopped by to make sure everything was ok. The piano bar is an added bonus - the piano player is lots of fun and happy to play requests.
And oh - the steak! Heaven on a plate. Perfectly cooked, perfectly seasoned. Sublime. Great sides, too - especially the salads. Excellent wine list, including some marvelous vintages by the glass.
This is my very favorite Las Vegas restaurant.
