The secret to ordering from In-n-Out is the not so secret 'Secret' menu. Get your double double animal style, fries light well and a coke for around $7. Great burger at a great price and in my estimation the best fast food burger in the country.
Chipotle is a gr8 QSR for Mexican food junkie like me. You cannot go wrong by ordering any item, be it burrito, quesadilla etc. Be prepared for long line during business lunch hour 12-2. It is more consistent than Chilis.
I have been eating at McDonald for once weekly. It is a good experience. It is clean and fast
