I don't imagine they are very authentic, but are they close? I don't really know from Philly cheese steaks, but the few I've had in the City of Brotherly Love itself have been kind of underwhelming (granted, I've never had one from Tony Luke's or the other supposed classic). Anyway, my point being, I wish I could go back in time and not eat the sandwich I just got at High Stakes (on the Park Slope side of Flatbush Ave.). A gut bomb with no real redeeming qualities (though the waffle fries were delightful). If this version of the sandwich is even somewhat authentic, then it would only cement my belief that the Philadelphia Cheese Steak is the most over-rated local specialty in the land.
