Are you kidding me? $500??
I’d rather be satisfied with a simple $20-30 restaurant-chain meal and use the rest of the money on gear.
Yeah, it’s absolutely not a pre-race meal option. More like an “I just obliterated my PB and found a wad of money” type place. Or, in my case, a 5th (and soon to be 10th) wedding anniversary spot. Fancy, jacket and tie. And in the conversation for best Italian restaurant in the US. At least among the non Nick-Barkley types 
And especially not a place I’d do a pre-race group dinner, either. Anyway, congrats on your upcoming 10th.
By the way, isn’t this the ST forum, not Chowhound?
