I went two times. The first time it was a complete disaster bringing our order after 45 minutes and then when it finally came, it was wrong... I asked no Mayo, and still they put MAYO.
Second time: We ordered One Plain Burger; No Mayo; only the cheese and burger. The second order was Burger with NO Onions and no tomato. What did we get??? Burger with Mayo, and the other with Onions and Tomato. Are we speaking the same language??? because it appears to be not.... A note: when I returned my burger to be replaced with a NO Mayo one, they served me a regular burger and not like the one I ordered (which was large)....... I think they were hasty to correct their mistake which turned out to be a bigger mistake.
Further, I am not really digging their service. Although polite, but they are not passionate or excited... The taste is not out of the world at all, as I heard... It is less tasty than many other Burger joints that recently opened in Amman.
Frankly, I won't go again.
