Had a lovely dinner here tonight, been coming to Luz for years and never tried it, but will make it a regular place from now on! We sat inside which was very comfortable with the A/C but saw people fanning themselves outside so it may be worth requesting indoors (although it's August so very very hot anyway!). Pizzas are amazing and would highly recommend the lasagne which was also so delicious! Portion sizes are generous so would maybe suggest just getting main courses or sharing starters.
Only criticism is that the staff sometimes looked as though they were doing nothing, food was out on the kitchen side ready to be taken out and they just kept walking past/chatting. But would still definitely come back :)
