I echo Cheryl, Pete. First time in Arillas for 2 weeks I put on over a stone. They said I looked pregnant when I got back to England! Took months to lose it.
The food is amazing. We all have our favourites, but Thalassa and Graziella on the sea front both tick my boxes. And for fish, ask how to get to Tomas's (Vasalis I think) for the best fish in the area. But Brouklis, Amourada and all the others are wonderful as well. There is no such thing as dodgy food in Arillas as far as I am concerned.
You will have a fabulous time there, and as stated earlier by Joe, September is a perfect time. We went the last week october last year, and although quite a few places had closed, we still had a wonderful time. Bet you can't resist returning after you've sampled it all!
