Restaurant owners seldom give up their restaurants.They have a head waiter for wont of a better expression who takes it on.Very often they work with a regular chef. He will then hire the waiters,create the menu and run the operation.Arif,who a lot of people know runs Arena,there is a totally new menu this year.We have eaten there, THREE times this year and enjoyed the food and the atmosphere.I guess food tastes are subjective,but it is always consistently good,which I think most Brits expect.Good eating.
