I've been going to Penang for years and usually get the same standby dishes--Buddhist yam pot; mango chicken (or shrimp); nasi lemak; roti canai. I've also seen recs on this board for the mee siam and the eggplant with basil, as well as the bone-in chicken curry.
But their menu is so enormous that I'm sure I'm missing some great dishes. Any recommendations for other excellent things to eat at Penang? Thanks!
