In a section of Omega you'll find an unassuming building, the only sign is the literal one over the door:

Tldr: Here's a bot to have fun with some of the aliens in Mass Effect. Currently there's Asari, Turian, Drell, Quarians, Hanar, Volus, Batarians, Elcor, Vorcha and Krogan. Might add more if it's requested.

Have fun!
