Angel Stadium Diamond Club

My brother has been my mom’s (87) personal caretaker post hospitalization for the last few weeks. She’s finally in a place where he can get away for a few hours. He likes Angel games and usually sits @ 514 but I want to thank him with better seats and access to nice dining. I don’t know much about the stadium. Is the Diamond Club the only nice dining experience? And is that included if you buy diamond field seats? Any other options? We’d probably go midweek this week. Appreciate any suggestions.
