Si Jang's hands down the best Korean restaurant in Vegas. If you're in town and are looking for a Korean cuisine you won't be disappointed. Menu is extensive and portion sizes are great. There is also a shared dish section in the menu. From the looks of the tables around me, the bo-ssam seems to be the most popular followed by the braised back ribs. I ordered the "dol-pan" (hot stone plate) and was not disappointed. It stayed hot until I finished it and tasted amazing!
I recommend everyone to drop by; There's an option for everyone :)
