Londoners: Need a Restaurant Suggestion

[NakaNaka]

Hello Londoners or people who have spent time here. I need a restaurant suggestion for a decent sized group of people. A fun place where we can drink/eat and not be rushed. Hopefully, not too pricey either. I've got places in mind that's decent for a group and fun but I feel we'll be rushed (Busba Eathai for example)

Thanks
