Under Settings – Currency Settings, you can only select whether the currency symbol is to be output before or after the price. Many plugins also support a selection with or without a space (e.g. 10 € instead of 10€). Would it be possible to add this option in one of the next update versions?
Currently, we have helped ourselves by simply adding the following change in line 425 of /wp-content/plugins/mp-restaurant-menu/classes/models/settings/class-settings.php: 'EUR' => ' €', – of course, this also works for other currencies, but it is awkward 🙂
