Are you sure, you did look well? It is on the same premises where Acuna is located. Coming from Siliman going North it is on the left side. You have missed it when reaching the junction where you go to the right to the sea.
Nevas pizza sign and the corner store with outside seating on the opposite side of the road is also hard to miss.
It is set back from the main highway, and no large signs when dark so easy to miss. I believe there is a vet clinic next door.
Yep, the vet office is Animal Wellness, who's sign is much more noticeable than Sofia's, just to its left in the same parking lot. Pretty good wine selection and it's part of the Times Mercantile group, but you need to be patient. The sales staff of 1 rarely shows up at 10, closes promptly at noon and doesn't reopen until 2. And as at many Dumaguete businesses, inventory control is almost non-existent, and our favorite house wine (yellow tail) is often "OOS." Sometimes find it at Times downtown (Locsin?) or even Robinsons.
