I go to Costa occasionally, the car park outside Everlast is deceptively large even with Costa there. It was, after all, built for a 10 screen multiplex cinema in mind. Couple that with the plans to knock down the old F&B restaurant for more spaces and they’ll probably be fine.
It’s more the issues around leaving the site and potential anti-social issues in the evening given that end of car park has become the “new” boy racer hangout.
