Staying at Mirage in a month and am new to my Vegas. Have been playing around with it for a month or so and he enough to hit my three rewards for the rolling 30 days. Went with two for one lunch buffet Mirage (easy since staying on site), buy one get one free entree at Portofini, and two for one lunch buffet Bellagio. Thoughts on value for this? I've never eaten at any of these places, are they good?
