I came in during lunch and we had to wait to be seated for a party of 3 for about 10 minutes. From there we waited for our drinks for 5 minutes and we have been waiting for someone to take our order for about half an hour. After waiting we witnessed tables who sat AFTER us getting their food. So we decided to not dine in anymore. It was hard enough to wait in general but we had to wait for the server to come to let him know we weren't dining in anymore. He came to our table and asked, "did you guys order already?" And I said, "no" and that we were actually not going to dine in anymore and he asked, "why are you leaving?" And I explained that we have been waiting for half an hour just to take our order and even flagging him down he didn't come to us. So we felt like we could be at another restaurant where they'll be able to serve us effectively. Then another customer comes up to him while we were leaving saying that her table has been waiting for their check for over 1 hour and he just said, "okay." Then walked away quickly. My party and I left, the customer service wasn't great and attentive as it used to be. I don't recommend Jjanga to anyone anymore. Seems like their staff isn't amazing as it was before.
