Came here a few weeks ago to try one if their burgers and gelato samples. The experience left a bad taste in my mouth (quite possibly literally), as the whole dining room had to be subjected to a loud argument that was held between the chef and the person running the cash/gelato bar. The topic of the argument was regarding a sanitation issue, which is probably the last thing that you'd want to hear about from the people who just made your food. Hence, I will not be eating here again, even though the cashier did apologize to everyone afterwards...
Despite the disturbing incident, the Master Burger I had here was average at best. It looked sizable and well made, but tasted mostly dry and the patty was nothing special. I sampled the Bailey's gelato and it was quite tasty-made with real Bailey's I believe.
Overall, this place is probably overhyped as there are better burger joints in this city. The final review rating is undeniable 1 star based on my whole experience.
