If you're not a buffet kind of person, I definitely think you'll enjoy Jiko more. Food's wonderful at both, but Jiko is rather upscale and there's more attention to detail and dish presentation. It's so easy to overeat at Boma with all the different flavors. We're not buffet people at all, and we ate there once. I swear, it took our group a couple days to recover from being so bloated and full!
