Romantic dinner? Jiko--excellent food, great service, upscale ambiance, great wine list
Casual dinner? Sanaa--very good food, reasonably priced, good service, and also good wine list. If
you go before dark (early dinner), chances are you'll see animals outside the floor to ceiling windows
Bang for buck dinner? Boma--solid food but lots of it, plenty of variety, still just a buffet in the end
