I describe a (conjectural) relation between moduli spaces of framed sheaves on some 2-dimensional root toric stacks and Nakajima cyclic quiver varieties. If time permits, I will discuss an application of this relation to the study of the Alday-Gaiotto-Tachikawa conjecture for gauge theories on A- type ALE spaces.
