We investigate sub-AdS scale locality in a weakly coupled toy model of the AdS_3/CFT_2 correspondence. We find that this simple model has the correct density of states at low and high energies to be dual to Einstein gravity coupled to matter in AdS_3. Bulk correlation functions also have the correct behavior at leading order in the large N expansion, but non-local effects emerge at order 1/N. Our analysis leads to the conjecture that any large N CFT_2 that is modular invariant and has the right
