We walked our way back on foot because we decided to not buy the travelcard for the next day. We had become pretty hungry after having spent about 2 hours in the park. It had also gotten dark and all the cafes we saw on the way either didn’t have a menu in English or didn’t accept cards. So, make sure to take some cash with you, even if you have plans to pay for everything with your card. Finally we ended up at a Chinese restaurant with affordable prices.
