Private dining rooms in London for 20 – 30 guests

The most frequent size of event booked on this site, the split between corporate and private functions is quite evenly balanced. Events range from business lunches, corporate entertainment, team celebrations, leaving do’s, networking and office Christmas parties to birthday bashes, family celebrations and casual friend get togethers.
Whatever the occasion, there are numerous London venues with stunning private rooms of this size from elegant and refined fine dining restaurants to funky and informal gastropubs and chic bars.
Many semi-private spaces can also be hired exclusively, which is worth considering if you are arranging a drinks reception or event that would enjoy the buzz of the wider restaurant – but obviously not suitable if speeches are planned!
Some private dining rooms for this number of guests will have space for a pre-dinner reception or may allow guests a sectioned off area of the bar, but some don’t have the room so do ensure the venue has enough space for all your needs throughout the function.
Top Tip: Many of London’s most iconic restaurants have private rooms this size but they all too often go unnoticed. We recommend checking out your favourite restaurant and just asking the question!
