Friday night bottomless menu, dinner and party atmosphere from 9pm

Saturday nights
Dinner, cocktails and live atmosphere
Saturday evening is for groups, celebrations and cocktails around dinner, with a polished restaurant-bar atmosphere for a full night out.
Dinner first, then cocktails and a late-night atmosphere from 9pm.
Mamma Mia, bongo brunches and other dated party nights can be added once and then appear in the right places automatically.
