A great local restaurant is the Frontier. It is across the street from UNM. They serve local New Mexican-style food as well as burgers and fries. They are open 24 hrs. and are very informal and inexpensive. You order at the counter and then take your food to the table. They have fresh-squeezed orange juice that we all love. If you are looking for a fine dining experience this is NOT it, but the food is good and you don't have to worry about your kids disturbing anyone.
Another restaurant is Flying Star. The Flying Star is a local hangout that used to be called Double Rainbow. All walks of life hang out here. You order at the counter and then the food is brought to you. They have a huge variety of food from Asian to American to Mexican. They have fabulous baked goods that are made locally. They are open 6 am to 11 pm, so you can have an early breakfast if your kids are still on another time zone. It is a bit pricey, but the food is really yummy and casual enough to enjoy a meal with the kids.
