The Aja Steak House charges $18/oz for their kobe steak. So, it's not hard at all to spend $200 by yourself for a complete with wine. Anyway, even David Burke's Primehouse (arguably the best steak joint in the city right now) is going to hit you up for about $75 for the steak alone, so a nice dinner for two with wine is easily a $200 meal. Benjamming, are you restricted to places that are within walking distance of the Mag Mile strip? What hotel will you be using?
