An iconic hotel that has hosted everyone from Churchill to Oscar Wilde, Hotel Cafe Royal has loads of options for events of all shapes and sizes. Depending what sort of anniversary bash you’re planning, you could plump for the regency-style Pompadour ballroom, or the plush Oscar Wilde Lounge, which has its own grand piano. The dead central location is also pretty handy, as Hotel Cafe Royal is just a minute’s walk from Piccadilly Circus.
