I Love Good Beer

Can someone recommend a beer similar to Warsteiner Oktoberfest? I have hated every single beer I have ever tried (hate is a strong word, some are somewhat okay) but this is the only beer I genuinely enjoy. I usually hate alcohol period.
My family and I went to a German restaurant and my dad ordered that beer and I tried some as I usually do. Went back twice and had my own - The only beer where I can drink the entire thing and enjoy it. And would like to find other more accessible beer like it. Since I usually don't like beer, I know nothing about it so I have no idea where to start. Doesn't have to be a Oktoberfest beer just anything that tastes like the one above.

tl;dr
Can someone recommend a beer similar to Warsteiner Oktoberfest?

Thanks!
