For a rehearsal dinner that will be remembered for it's fun and irreverent style - consider a night of fresh Tex Mex or Mexican fare! You can either opt to create all of it on your own or bits and pieces. Have a favorite guacamole recipe? Perfect - you make that and have a friend, caterer, or favorite local mexican restaurant do the rest. Tacos, enchiladas, rice and beans - fresh tomatoes, peppers, corn salsa - the possibilities are endless. Think out of the box and add fish tacos and shrimp tacos. Try making a fresh white sangria out of a light white wine like a pinot grigio or a gazala. Now add some fresh oranges, limes and lemons and let it settle and chill for a few hours. Some guests might prefer a great Mexican beer such as Tecate or Corona and or course it wouldn't be a party without a margarita or two!
For decor go a bit different from a traditional Mexican palette - hot corals, reds, kiwi, papaya and mango will add a more modern flare and most of these colors are available in linen.
By all means throw in a mariachi band for a bit but please - no Pinatas!
If you have the budget there are companies that will come out to your home or business and set up a portable restaurant to make your party more like a street fair.
