The family are coming over to Costa Teguise at the end of July,
its my 60th and my wifes 50th,
Where would be a nice restaurant to have a dinner to celebrate,
we like traditional food but some in our group will try anything,it will be a family of 8 with 2 children aged 8 and 4 included,would somewhere do a cake to top the meal off,
thanks in advance for any ideas.

Depends on what you want. I would be inclined to Montmartre which is on the inland road near Playa Bastian. Some people like Villa Toledo (lovely situation overlooking the sea) but reports of the food vary. Oscars opposite the Santa Rosa complex also has a decent reputation.
Good luck

as in said in the first post,a mixture of traditional food and anything else,
maybe somewhere where they will throw in a cake.
