Short answer: at Byter, restaurant marketing starts at £750 a month plus VAT and most London restaurants sit between £1,500 and £3,000 a month. Content shoots are priced separately, from £650 plus VAT for a half day. Packages run on a six-month term, then month to month. Ad spend is paid straight to Google or Meta and is not part of the fee.
