Cosmo Cafe

(it's actually a diner but cosmo cafe sounds nicer than cosmo diner)

tl;dr - diner is located in space and serves all kinds customers from different universes, timelines, etc. Ends up "adopting" two "space angels".

(disclaimer - Gloria and Jason's bios are HORRIBLY outdated, but does have some relevant lore information. Basically uh if something doesn't add up or you wanna do something totally different go for it)
