Birthdays at Diego's
Birthdays worth the candles
18th, 30th, 50th, 70th: we have thrown them all. A private room, a rooftop, charcoal-grilled feasts and a team that makes a proper fuss of the birthday guest. Who, by the way, eats free.
- Birthday guest eats free
- Fiesta Room seats 40
- Decorations welcome
- Sparklers included
Milestone birthdays are our speciality
Light-up numbers, balloon arches, boho table styling or just a long table of your favourite people: the Fiesta Room takes it all, and the terrace does summer birthdays like nowhere else in Southampton.
The birthday guest eats free
Celebrate with us and the birthday meal is on the house, with sparklers and a proper Diego's send-off. Just tell us it's a birthday when you enquire. T&Cs apply.
Food that feeds a party
Bottomless wings for the big appetites, sharing platters for the table, cocktails at 2 for £15 during Amigo Hour. Nobody leaves a Diego's birthday hungry.

Good to know
Your questions, answered
Does the birthday person really eat free?
Yes. Celebrate your birthday with us and the birthday guest's meal is free, with sparklers to finish. Just mention the birthday when you enquire or book. T&Cs apply.
Can we decorate the room for a birthday?
Absolutely. Balloons, banners, light-up numbers and your own cake are all welcome in the Fiesta Room, and we will help you set up before your guests arrive.
How many people can I invite?
The Fiesta Room seats up to 40. Larger group tables in the main restaurant work brilliantly for 10 to 25, and exclusive hire takes up to 60.
Do you do anything for the birthday moment?
We bring the cake out with sparklers and make the moment happen. Tell us the timing you want and we will build the evening around it.
