The Guinea Grill is a tiny pub on Bruton Place in Mayfair, and perhaps owing to its size or the fact that it’s a bit out of the way, it doesn’t often attract huge crowds like other Mayfair pubs do. People do come out of their way for the food here though. They serve a limited menu of pie and oysters in the bar, as well as sandwiches for lunch, but if you’re looking for somewhere more spacious, you should head to the very old-fashioned and sedate restaurant in the back. Pies and oysters are still on the menu, but what you really want to get involved in are their excellent - but pricey - steaks.
