Going on a Business Trip

I'm going on a business trip next week from Houston to Los Angeles and I'm worried about my diet while I'm gone - specifically getting enough protein. Fluids shouldn't be an issue since there'll be water everywhere. I figure I can find something to eat at most restaurants. But I've been drinking ready-made Isopure Protein Drinks and it isn't feasible to take those with me. The protein powders I tried right after my surgery weren't at all good to me. Can anyone recommend tasty protein powders and tell me where I can get them? Also any recommendations to help me on my trip would be greatly appreciated.
