I really enjoyed this place (Trang Tien location). Had some good friends with us. We sat upstairs on the outdoor balcony. I don't know too much about steak, but it was very delicious. A friend's steak had a lot of marbling, so he returned it and the manager accepted it.
The only thing I would say is that the foreign manager says hello and is kind only to foreigners. I usually don't notice such things, but unfortunately human nature works in that once you notice it for the first time, you keep noticing such things afterwards.
perhaps there's some reason behind this. locals don't order much or always complain about their food, etc. Still feels like a sting in the face though.
