I have not seen Gabbys mentioned here. I believe it is only opened for breakfast and lunch, not dinner, but very enjoyable environment and the food is good, basic and simple but good. Price is also good. Popular also, which attests to the quality of the food.
It's been a while but they do have several mentions on the forum. They do have some good food there. I have them on the main site as well. There is a map there if you are not familiar with the place. P.S. what ever happened to @shadow? It's been awhile.
I believe there is the old Gabbys, and the new Gabbys. I am referring to the new Gabbys, with the B&B, established this year . Sorry, I did a search and came up with one very old reference only.
Head North out of town on the National Highway, past Kangs, when you get to the first Shell Service Station, on the left, turn left there, and travel down about 200 metres or so, past ISUZU on the left, and you will find Gabbys , on the left. Not the Shell SS near the Airport on the right, if you get there you have gone too far.
