Oh man, I forgot they don't have tri-tip in other states really. It's just a cut of beef, nothing fancy, but it's reasonably priced and tastes great, here is a picture:

If you search on www.google.com for tri-tip or Santa Maria tri-tip, you'll find more info.

Thanks for posting your lunch tips, I think this could be a fun topic :)
