Salaam All

I would like to ask for suggestions as I know multiple minds are better than one I am struggling to think of a venue in east/north central east london.

I require a private room with a seperate entrance for around 40 people for a Nikah

After some consideration I thought the best option given the small number of people is a room possibly attached to a restaurant a banqueting hall as it will already look presentable and there is no need to find a caterer for food.

My requirements are if possible

onsite parking
seperate private entrance - without having to walk through the restaurant,

Thank You for all of your suggestions
