I really like the Indian restaurant next door, the Royal Indian Cuisine. Excellent curries and generous drinks.
The restaurants on the opposite side of the road in Quinta Shopping are all just ok.

I’ve had dinner quite a few times at Louro and find it very overpriced, underwhelming, service hit and miss, no good wines and food inconsistent.
I ordered the Angus steak last time I stayed in May asked for medium rare, received well done. Sent it back obviously, another 40 minutes wait so the rest of my party had finished their meals and the steak was only medium if I’m being generous. Was too fed up to complain further, ate just the middle, but for €45 one would expect a chef to be able to cook a steak. So avoid any red meat if you do decide to go. Fish is a good option ( except the cod in salt crust another expensive tourist trap with hardly any food).

I also agree with avoiding Gusto the Michelin star restaurant in site. Went once and left hungry and very out of pocket.
