I couldn't come to Vegas and not try Burgr by Gordon Ramsay.
Overall, I'm happy we went, the burgers are delicious and the prices reasonable.
It doesn't beat the best, but easily lands in my top five of all times. The main downside is that a great burger has to pack all his qualities into a format small enough to wrap, take away, and eat with one hand.
Being served on a plate is a red flag in my book. Special mention to the bun though, really good.
