Peel Hunt analyst Douglas Jack gives his view on the prospects for The Restaurant Group, which is due to report on Q1 trading next week. He says that while Wagamama’s like-for-like sales are likely to flatter for a while yet, the cost of labour inflation and broadly flat lfls in the rest of the company leaves the brand with little room to slow. He also asks whether it is time for companies like TRG to break out their in-store and delivery revenues and lfl sales.
