I'm glad I'm the 2nd reviewer of this place. After a headache getting into town and finding out our original hotel reservation was cancelled at Monte Carlo (long long story), we headed over to Excalibur the next day for the duration of our stay for CES 2012. Hungry and tired, headed over to ABX...and the hamburgers were delicious. They had so many choices of sauces...I'd say close to 12-16 types ranging from creamy, spicy, herb infused, and just many more...it was hard to choose just one. It's a half a lb of meat...which I think is a lot...and all the toppings you'd like. You customize your order and they'll make it for you on the spot. They have turkey burger options as well. The place is clean, trendy, and very Americana...if I was craving a hamburger without the Vegas price tag, this is the place to go! Thank you for being there at our most hungriest time and after a long day of work and headache.
