We knew there was pork belly on the burger but only because of watching
YouTube videos before hand. You shouldn't have to do that, and it most definitely should be listed on the menu.
Honestly, we didn't have the greatest experience when we had lunch at Steakhouse 71. I've been hesitant to post this as everyone raves about it, but our service was pretty bad. The food was good though, so we are going to give it a second chance in December to see if they've worked out the kinks. Our poor server was very sweet, but one of the first things he said to us was that it was his first day working the lunch service and it definitely showed. He just seemed overwhelmed and kind of confused about everything. That really shouldn't happen if the staff is properly trained. Our appetizer ended up showing up 10 minutes after our entrees and the cocktails we ordered at the very beginning came after we were completely through with the meal. All in all service was just very slow and the restaurant was not that full.
After reading the OP's post it really seems that training of the staff is an issue there. It's only been open a short time, so as I said above we are going to give it a second chance. Most people seem to have loved it so maybe we just got unlucky. Who knows?
