Outdoor Reception/private Catering

Hi! I just recently got engaged and we’re starting to plan our wedding. We live in San Diego, CA and want to have our wedding here. We really want an outdoor reception, the look we have envisioned is “romantic and family get together”. Ideally I’d love to have it in my Uncles backyard but we just can’t get it all to fit. We really want that vibe of going to your family members get together to celebrate. Although we want romantic, we don’t want formal. The issue we’re running into isn’t an outdoor venue but an outdoor venue that we could bring in our own catering because we love the idea of having a taquero. Neither of us are fans of traditional wedding food, at all. So we want a fun relaxed delicious dinner of a taquero, which everyone will love. Any suggestions on a venue where I can make both requests (outdoor and taquero) happen?
