I haven't eaten there (yet), so of course take this with a grain of salt.
Sparks is literaly around the corner, when they start cooking we can smell it. Every day while waiting for the wife to come and pick me up and do the driver change and all that, I see limos dropping off people. It's unusual for a restaurant to have that much traffic that early in the evening, and the people usually look like they can eat where ever they want. I figure the food must be pretty good to be that busy, none of the other steak houses within a block or two have that kind of traffic.
The benefit of course is no matter what time we get out of here, and in any weather, if needed, there are cabs on the corner.
