Just chiming in to say that the Big Tebowski is spot on about food in London. It’s like New York City in terms of quality and types of cuisines available. The only thing I’d say is that Mexican is a bit lacking here compared to the US and Colorado in particular (I’m from there, but in London for a long time). We have some decent options here, but I wouldn’t put them on the same level as in CO.
There’s definitely some amazing bbq places popping up, which is a welcome new trend.
Let me know which part of town you’ll be staying in and I will give you a list of some solid places to try while you’re here. It’s almost impossible to stay on top of all the delicious places that open up (street food or otherwise), but it’s a nice problem to have.
