I only spent one day in Cala'n Bosch and liked the look of La Marina when I strolled around the Lago. I don't usually eat out alone... but it did look inviting, so I took the plunge and went in for lunch on my own.
The waiter was very welcoming, clearing the extra place-setting without a comment, and assuring me it would be fine just to have a salad and a drink.
I choose the 'ensalada de pera' - which was quite substantial, including pear, Mahon cheese and crispy jamon as well as green leaves, and various shredded vegetables. Along with crusty bread, it was very fresh & tasty. The house dry white wine was a Torres, so I managed 2! The bill was about 14e, which I thought was very reasonable.
