  We study the discovery potential of string resonances decaying to $t\bar{t}$
final state at the LHC. We point out that top quark pair production is a
promising and an advantageous channel for studying such resonances, due to
their low Standard Model background and unique kinematics. We study the
invariant mass distribution and angular dependence of the top pair production
cross section via exchanges of string resonances. The mass ratios of these
resonances and the unusual angular distribution may help identify their
fundamental properties and distinguish them from other new physics. We find
that string resonances for a string scale below 4 TeV can be detected via the
$t\bar{t}$ channel, either from reconstructing the $t\bar{t}$ semi-leptonic
decay or recent techniques in identifying highly boosted tops.
