Looking for somewhere to eat tomorrow with 13 people and many dietary requirements…

Hola! I’m wondering if anyone would be able to suggest some restaurants in central Barcelona - near the sagrada or the gothic quarter - that would be able to meet the following requirements for a big group tomorrow….

We are 13 people
We want Spanish food, ideally tapas
We have two peanuts allergies, one person gluten free, one vegan, several vegetarians and a vegetarian who can’t eat mushrooms, avocado or red peppers 😅😅
Lunch or dinner tomorrow

Two members of the group are food writers, so if there’s somewhere that can cater to all that, has space for 13 tomorrow, and is actually genuinely good and worth seeking out - I’d be extremely grateful to know where you’d suggest!

Thank you very much in advance Redditors 🙏🏼
