My Airbnb was a good 20-25min walk down the lake from the city centre. It wasn't the most convenient location but luckily for quickly available food, there was a Don Luis around the corner. I'd read about this place but didn't realise it was so close. Once inside, there were "croissants" which were surprisingly very sweet and some delicious empanadas (with chicken or spinach) that were cold and they couldn't heat up. Even the bread options were quite limited especially for first thing in the morning. It seemed quite odd to have such a limited range.
Later in the day I discovered what happened. Further down the road towards town (about 15min walk) was the real Don Luis. A large space including half of it dining area. There were showcases of cakes, breads, savoury items that you expect from a large well reputed bakery. Of particular note were the exceptional pies of which I took two large slices home to reheat in the oven. One was chicken slivers with boiled eggs and the other spinach, vegetables and cheese. Both were excellent with a wealth of texture and flavour. What was more impressive was the pastry with soft and chewy on the bottom, crispy on top, and the perfect thick combination of both on the outer crust. Easily one of the best crusts I've had and very happy and indulgent to eat the crust alone.
