With the recent government guidelines on continued social distancing in restaurants, many will either have to continue focus on takeaway, or close completely if they were already small in size. However, even the bigger restaurants will still have to work at a 50% reduced capacity.
To meet the rules temporary changes will be required, including seated, table service only; screens between seating or tables; no standing at the bar; and a one-in-one-out system for toilets. Running costs will definitely be higher under these circumstances and it may perhaps not be feasible for all restaurants to continue trading in these circumstances.
Customer confidence is weak at the moment and the country is looking at a serious recession. So the harsh truth is that for many it is no longer a viable business.
