Restaurant recommend

Hi,
I just move to Mainz a week ago (so new!!), and I can't speak German.  I will have my friend come to visit me and she loves Schweineshaxe. Anyone here have any idea any place (during weekday) serve this dish for lunch before 11.30 AM. She has limited time due to her flight.She need to be at the train station around 12.15 PM.

In case there is no restaurant serve this dish during lunch, can you please recommend the place to buy (to go) and I can pick it up for her before 12.15PM.

Also she would love to walk from Mainz Romisches Theater station to Dom. Is it safe to walk around that area? She will arrive at the station around 8 AM by herself.

Thank you very much for your advise.
