We've lived in Leesburg for 4 years and we've always talked about trying Del Rio's, and we finally had the opportunity. The food was good, but not great. I had the lunch buffet and my wife had shrimp tacos. The buffet was a very good value for your money and the food was fresh and hot. They served free chips and salsa and were very proactive on replenishing our drinks and chips.
The interior is very dated and they could use an overhaul or redecoration, but overall the experience was decent. We're not sure we'll revisit anytime soon, but only because the atmosphere needs some sprucing up.
