Outdoor wedding appetizers/snacks

I think your reason for doing Mexican is super cute! There are lots of ways to make your food setup look elegant. I think the #1 thing is to have nice serving dishes for everything, not aluminum trays or plastic. You could use glass, wood or ceramic serving bowls and use trays or cake stands to add variety/texture. Little signs for each item is a nice addition.

I have worked for a caterer in the past and finding out the host's colors/theme is definitely part of planning the set up. So just let them know what you are thinking and they will be able to figure out the display (although, to me, rustic and modern are pretty much polar opposites, so that might be confusing!) .

Most caterers can do this easily. There are countless photo galleries on catering/restaurant websites and Pinterest that don't resemble a kids' party in the least. Honestly, as long as the food is good, I wouldn't worry about it or overthink.

Some nice ceramic bowls and platters that are colorful. I’d steer away from sombreros but you could do colorful table cloth even Mexican blanket if you have one. If you. An have more than one table with different food that would be cute. Add some greenery or flowers, maracas, candles, etc.
