If you want a nice night out in Albuquerque without traveling too far (or at all) from Old Town, take a trip to Antiquity. This is a really nice restaurant without the stuffiness that sometimes comes with that. It's in Old Town so it's mostly tourists, but I hear some locals come by for the great steak. It's mainly steak and seafood. My boyfriend had the shrimp scampi and liked it. I had the lobster tail, which was a little dry, but still good. The comfortable atmosphere made up for what may have been lacking in the food.
It was lovely. Like most of Old Town, it's an adobe building. But unlike many of those buildings, it's adobe inside as well. The restaurant is pretty small with excellent service. It had a short but nice wine list.
The dress is pretty casual. Not shorts-and- t-shirts-causual but you can wear jeans and sandals. It's probably not the best place for kids, unless they can sit still through dinner.
