It's not the latest kind of bread and the bakery is old, but somehow the bread is simple, nostalgic, and very delicious.
ご質問ありがとうございます。
"It's not the latest kind of bread"=「今時のパンではなく」
"and the bakery is old,"=「そしてパン屋は古い」
"but somehow the bread is simple, nostalgic, and very delicious."=「でもどこかそのパンは素朴で、懐かしくて、そしてとても美味しいです。」
ご参考に。
