Aquarius @ the renaissance Marina tower.
have you dined there?
we have been a few times.
it is not our favorite, as we are not overly wild of buffets (husband does live LaVista buffet) but Aquarius is pretty good.
they do have terrific seared tuna, a nice variety of meat/seafood and veggies.
their prices are moderate.
they have great breakfasts.....which is our favorite there.
