In Lisbon, I did a fantastic wine and charcuterie tasting at Lisbon winery. It was pricey, 85 euros, but well worth it to me! I did it the late afternoon after the Gulbenkian museum visit. An easy metro ride and 5 minute walk. It substituted for my dinner that night. I hope you get to stay at the Figueira by Beautique, our RS hotel in April. It was great. I also arrived early and thoroughly enjoyed a Culinary Backstreets food tour and an Eating Europe food tour-which I did the morning the tour started. I learned so much about Portugal and their food and wine on all of these tours. You're going to have a great time on this tour! The Tile Museum is really worth the bus ride out there - very easy to get to. Lisbon has great public transport. I also highly recommend the Taylor's port wine cellar tour when you get to Porto. It's worth the walk up the hill. I booked a ticket ahead of time online, but that was not really necessary. I went in April, so maybe that's a different story, but none of the places I ate at required a reservation ahead of time. I like being flexible depending on how big my lunch was! That often tended to be my biggest meal of the day, but others in the group going out for dinner never had a problem getting a table.
