Just got back from Vegas and had my 1st Shake Shack burger, was nice but not as nice as I think 5 guys is (Missus didn't like her chicken burger at all), I wanted to try the burgers at Charlie's bar in the Wynn but couldn't get past the Philly Steak sandwich, it was amazing and I would gladly replace a burger with that everytime.
Also had the Sage Fried Chicken Benedict in Hash House a Go Go, bleeding hell that thing was massive and so so tasty but I could only manage half of it (me and the missus should've shared in hindsight).
