Thai in Siam Square, Pratunam, Phloen Chit & Ratchathewi

The area surrounding the Victory Monument is home to heaps of simple restaurants selling spicy, rich 'boat noodles' – so-called because they used to be sold directly from boats that plied central Thailand's rivers and canals. Our pick of the lot is Toy, located at the edge of the canal at the northern end of Soi 18, Th Ratchawithi. No English-language menu.
