For seafood lover, try pondok pessangrahan in karapitan.
for batagor, my favorite is batagor abuy in lengkong.
for local sundanese food, you can try laksana or ampera restaurant, but be careful, the sambal VERY spicy one.
you can also try petis kangkung and lotek in kelenteng.
or you can go to cibadak, but only at night, a lot of hawkers food.

sundanese language tips:
sabaraha - how much
hatur nuhun - thank you
