I was really worried I gotta admit from some of the review but I came here anyway today and had the Rossini $60 burger.
I can tell you it's a combination of greasy, fatty flavors that I've never had before. You HAVE to salt it and add black crushed peppercorns AND the sauce they give you and I promise you it is the most extravagent burger (if you can even call it that at this point) you'll ever have. My wife had the surf & turf burger with lobster and asparagus...A-M-A-Z-I-N-G.
Now that's it's over it all was totally worth the bill. Don't buy this stuff if your strapped for cash...it's skews your opinion too much. Come and eat this if the prices don't scare you and you'll think it's the best lunch you've ever had. Period.
