Roberto's is a small place in the shopping center on the northwest corner of Rt 1 and Linton. It is technically a chain but this is the only one in Florida, the rest are out west. Ok, so the decor isn't exceptional- it's not dingy either.
If you're in the mood for some cheap eats, hit this place up and maybe get some Jarritos to drink. They have a few fresh salsas, including a mild green one that I like. I always order the carne asada beef chimichanga, but all the food is good. The chimi is a huge beast and it can feed me for two meals. It has chunks of beef, not shreds, and is perfectly flavored. This place also serves breakfast.
