Driving down Highway 307 south of Playa del Carmen toward Tulum is an area known as Punta Soliman. You will see a sign on the left advertising Oscar y Lalo's Restaurant. Turn left at the sign onto an unpaved road. The road can be somewhat bumpy although we had no problems. You arrive at Oscar y Lalo's parking lot in about five minutes.
The restaurant is under an open air palapa. There are several tables outside under the palm trees. Hammocks are available right beside the tables!! This is a wonderful relaxed atmosphere.
The menu has several items, primarily seafood; however, there are some chicken and beef available as well. The prices at Oscar y Lalo's are more expensive than I would have imagined. The fish dishes and fajitas are "normal" prices, but other dishes are pricey. For example, the grilled shrimp was over $30. The serving sizes are acceptable, but I have certainly had more in other places. The quality of the food is good, but not spectacular.
Would I return? Absolutely. I highly recommend this place, but more for the atmosphere than the food.
