tl;dr: I wouldn't necessarily travel to eat here but if you are already at the Westgate then this is a solid choice breakfast or lunch. True Rating: 3.5
Full: The prior neggy reviews do not appear to be justified.
Sid's, no longer a 24-hour eatery, is clearly aiming for an upscale feel which it (mostly) delivers. Prices are certainly upscale (welcome to Vegas, baby) and the welcome I received upon arrival from hostess Jeanine was very warm and solicitous.
Unfortunately the waitstaff service was slow (Jeanine actually had scramble from the front podium to take my order) but this is likely a case of understaffing.
The food quality was above standard. I came in for lunch and had the "Black and Blue" steak sandwich ($15) with curly fries which I recommend. All day breakfast is also a plus.
