This does not sound like the ship we just spent 32 days on.
The burgers at the Pool Grill were not thin, gray discs, but nice thick and well grilled. They are cooking on an electric flattop, so you can't expect to get the same flavor as from a wood or charcoal grill. Every time I got a burger, the bun was nicely toasted.
The only issue I had was one evening in the Restaurant, I ordered the New York strip steak medium well and it came out on the rare side of medium. I had to send the second one back, too as it was even less cooked than the first. They finally got it right on the third try. On all previous VO cruises, the steak always came out exactly the way I ordered.
There will be hiccups occasionally, just don't let it be the dominant thing that you take away from your cruise.
Kate, the Cruise Director, was the best we have had yet. I loved her Scottish accent.
