We ate in Tony Roma's a couple of times and highly recommend it. Our bills were actually cheaper here than in the lower-end Ponderosa. The quality of food is very good. I would highly recommned the chicken flatbread as a starter. The ribs, burgers and steaks all went down really well with the family and portion sizes are big, so take a box home for the next days lunch. The only food we tried that didn't work was the tempura asparagus. It was a bit too greasy and the asparagus just didn't need the addition.
The staff were really attentive and helpful with selection. When we were there, there were a number of staff from Belfast over training and they were very friendly.
It's not fine dining, but it is good grub and service at an affordable price.
