I just spent 9 days touring around Puerto Vallarta, Tequila Jalisco (the epicenter of production which gave its name to the Magic Juice), and Guadalajara. It was a travel conference where I met some great people who will be friends long after we get over our jet lag.
We visited several different and fabulous restaurants during that time, and I really did lose 4 lbs during the trip. My thinking is that the food was clean, local and fresh. The new mexican cuisine is different that we are predisposed to believe and very interesting on the palate.
