Of course, Mr Miami isn't his real name, he's actually called Nick Alexander and whilst he grew up Stateside, his mother is Jamaican British, so he's been across the pond before.
Now, there are some stereotypes amongst the other nations of the world about what to expect from British cuisine, but the fayre in The Nickelodeon in Wolverhampton certainly seems to have lived up to expectations.
Nick told LADbible: "In regards to food, the common consensus in the states is that British food isn't great, so I came with seasonings expecting the food to be bland."
"What sparked me to say it was like a Christmas dinner was the turkey and stuffing, but in comparison to our Christmas dinner back home this was a plate for a 10-13-year-old, if I'm honest.
"But it's not as bad as I thought. I think we love our sauces and artificial flavours a whole lot in America if I'm honest. Over here y'all just like things a little plainer I think."
What more of a ringing endorsement can we ask for other than 'not as bad as I thought', right?
He continued: "I started documenting [the meals] randomly. if I'm honest. My friend Rosalie in Miami is always asking me what the food is like for when they come to visit, so she kind of sparked the idea.
"British food is always getting a bad rep so I decided instead of highlighting the negative I'll highlight the positive and here we are."
In another review, he sets his laser sights on Costa Coffee and appears to be a big fan of the high street coffee shop.
Since the carvery video was released, it's been viewed over a million times, and liked by nearly 300,000 people. That's a big deal for Nick.
He told us: "The online response had been overwhelming, I didn't expect it to go viral the way it did.
"I've even started raising money for the homeless because helping people is what I'm really passionate about, and because I was homeless before."
Incidentally, you can - and probably should - aid Nick's efforts to help the homeless right here.
Next up, Mr Miami intends to turn his attentions to some of the other types of cuisine that the UK has to offer.
Hey, where else is there to do after a carvery and a Costa Coffee?
Well, Nick says he wants to try London's pie, mash, and liquor, but also eat at the top of The Shard. Those are going to be two massively varied experiences, that's for sure.
Nick concluded: "I just want to say thank you to the UK for making me go viral.
"The UK makes up 99 percent of my TikTok followers - and I can't wait to try more food and visit more places around the country, I love it here."
