Visited Tavira Lounge on a couple of occassions (easy lunch and then after-dinner drinks). Both times, we had a very favourable experience. We also had children with us and they were well looked-after as well. The staff is friendly enough and the service decent. Lunch was delicious for all (salads, soups and sandwiches). There's also a large of selection of pastries and sweets for all.
If you take a spot towards the back of the lounge, you can look out on the river.
