I found Cartagena Culinary Tours and booked with them. This is what they sent me prior to booking:
Thank you for contacting Cartagena Culinary Tours! Sorry for delay in replying, but had some issues with wifi maintenance. We have two tours available for lunch at 12pm, both in the Historic Center, SANTO DOMINGO tour with 3 restaurant stops, duration of 2.5 hour at US$89.00 + tax and SAN DIEGO tour with 4 restaurant stops and a duration of 3.5 hours with a price of US$110.00 + tax and since your cruise ship leaves port at 3pm we recommend the later tour or Santo Domingo which for Cruise ship passengers we start one hour earlier at 11am and we will get you in a taxi at 1pm at the latest so you can be in port an hour earlier before departure. Private tours have an additional cost of US$30.00 pp and it will only be for passengers from same cruise ship and usually our clients help us post ad on Cruise Critic board. We have a pick up courtesy for private tours which have a maximum of 8 people. As soon as you confirm we will be sending a PayPal invoice.
Looking forward for your reply.
