Um, sorry to say, this might be one of the few places I need to pan.
I was excited about the concept of a grilled cheese-centric place opening in Vegas a la Manhattan's lamented Grilled Cheese NYC. Unfortunately, Dad's really disappoints. First of all most of the menu isn't even grilled cheese varieties, but other sandwiches with cheese on them...BFD.
Secondly, the grilled cheese variety I ordered (The Godfather?) wasn't even that cheesy! I've had more impressive Grilled Cheese at Ruby's Diner (a chain).
Thirdly, the tomato soup was strongly recommended...it was thick and sweet and reminded my dining companion of the sauce that comes with Franco-American's Spaghetti-Os.
In short: Out of the way, and not worth the effort. Sorry, Dad.
