About

If you're looking for a private dining option for your next event in central London, check out Casa's Mayfair branch. If you're not already familiar with Casa, this small London-based chain showcases the best of Algarvian cuisine and culture, with a menu full of traditional Portuguese dishes, with influences from Mozambique and Angola, too. 

While the brand is known for boasting some great private dining rooms across its locations, Mayfair has the most options by far. And, with a brilliant spot in the heart of the West End, tucked down Heddon Street and surrounded by buzzy bars and pubs, it's a no brainer. 

Casa Mayfair's ground floor dining room is large and spacious with high ceilings and plenty of natural light. Across the walls you'll notice rustic, exposed brickwork and terracotta pottery decorating the space, collected from across Portugal. Atmospheric lighting gives the place an ambient feel while large, potted plants bring the inside in. You're welcome to book larger tables here but you can also take over the entire restaurant which has a capacity of 125 guests seated, 40 in the bar area or 80 outside in the terrace. 

Sol and Mar are two private dining spaces which can be seperated or used together. Seperately, they have capacity for 14 people each, making them ideal for smaller, more intimate get-togethers, or take over the whole space for 34 people in total. 

Additionally, The Green Room Bar is a beautiful, atmospheric space with room for between 40 to 100 people. Here, you can bring your own music or work with the events team to organise a DJ or live band. There's also the opportunity to decorate and transform the room however you would like, whether than be with balloons, flowers or banners.

He made it all seamless. So please do give him our thanks again.    Thanks!
