We had a $50 food credit to use and thought that Burger Bar would give us the best bang for our buck. Burger Bar is located one level 2 in the Shoppes area of Mandalay Bay, not in the Fleur/1oak nightclub area. Got there for an early dinner on a Saturday and there was no wait. We called to put our name down but they said it was first come, first serve. I guess they changed their policy based on previous Yelp reviews where people made reservations.
We were seated at a booth which had a USB/110 on the wall! Perfect if you have your cable on you and have been depleting your battery while wandering around Vegas all day! Being the purist that I am, I went for taste and ordered the Kobe burger for $18 and added foie gras $13 which I can't get in California. The burgers come with lettuce, tomato, red onion and a pickle. K got the regular Angus for $10 with various toppings. We also got skinny fries for $4 and mozzarella sticks $7(!). The foie gras was pretty good and a decent portion for $13. It wasn't the best I had but it doesn't matter as much when you're smashing it on a burger. I had to have a few initial stand-alone bites. My burger was so juicy and flavorful, I just constructed it with the lettuce and tomato and that pretty much made it. Figured if I was paying $18 for a burger then I wanted to taste the burger and not a bunch of condiments. It was super filling too.
I had a few of the skinny fries which were just fries. K loved his mozzarella sticks but I don't think it's worth it for $7.
We had great service although when we asked about different menu items, she answered "awesome" to it all. Which was true but just hard to gauge the level of awesomeness for each item.
Prices weren't cheap but not too outrageous. I felt for a hotel restaurant and location, it was a good experience.
