There are many “techniques” for finding great restaurants wherever you go. You can use Instagram, Yelp, TripAdvisor, but you can also use Google maps. This is how I found Caravan at Exmouth. I searched on the map all restaurants around our hotel. Once I found it, I looked at their website and the customer reviews.
They serve brunch during the weekend, but if you are not in the mood for a brunch, they have a solid all day menu. We arrived at 10 am, and people were already waiting for it to open.
The coffee is excellent ! They roast it by themselves FYI ! The avocado toast is delicious too. Honestly, I was not a big fan of the pancakes, the lemon curd was a little bit too much for my taste. However, the rest of the food was really good. Plus, it has great prices for London !
I highly recommend it if you are looking for an excellent coffee and breakfast. I did not try the rest of the menu, so I can only endorse the breakfast/brunch. It is located in a relatively quiet but nice area of London (Farringdon). There are many attractions at a walking distance, such as the British Museum.
If you ever go to London and decide to try Caravan, let me know!
