"A magical and unusual secret garden in the heart of London. Hopefully, the sun will shine and your guests can enjoy the verdant plantlife. If not, there is a variety of function rooms to hire. Alternatively, get a marquee from Claremont Marquees, the garden's chosen provider. Caterers must be chosen from the Garden's approved list.
Marquees can seat a maximum of 325; the gardens can cater for up to 400 for drinks (up to 550 with a special licence)."
