I explore the Galactic Center as a playground for probing strong field gravity observationally within the next 20 years. I summarize some of the existing observational data, highlighting mysteries that need to be resolved to gain a full understanding of gravitation and matter in this region. Recent observations of the gamma-ray excess around the Galactic Center by the FERMI Gamma-Ray Space is consistent with emission from some forms of dark matter annihilation. An equally plausible explanation is emission by pulsars. To date however very few pulsars have been directly detected around Sgr A*. I discuss how this situation may change with the advent of MeerKAT and HIRAX and the implication these observations will have for our understanding of the region.
