Was going through #thestruggle after pretty much not eating all day and needing to get SOMETHING in my system. Luckily for me, the Palazzo is still connected to the Grand Canal Shoppes. Which just so happens to contain the food court that's actually reasonable in terms of price and options.
Johnny Rockets is probably the best option of all of them, which honestly really doesn't say all that much for the rest of the food court. But the Smoke House Double got the job done for me right before hitting the club. Gotta get them cals so that I'm not dying on the dance floor!
