I've had some weird stuff, especially when I went to Europe and Western Asia. Best damn meal I ever had though was from a food stand in Grand Central Station. Paid $5 for a salad and a fruit shake. That was the best goddamn salad and shake I have ever had the pleasure of shoving into my mouth.
It helped that I talked to the old guy that owned the thing too. Chatted for a good bit while I ate, told him I'd come back if I was ever in town. That was three years ago. I recently went back last month to visit some friends. Went to the same little stand in the same little corner and had another great -blam!-ing meal.
