Luke's has been a mainstay in Tucson for years, now with 3 locations throughout town, you can visit from most parts of town. Subs stuffed fat with meat and cheese, dripping with Italian dressing, my husband can barely get one down and usually does not need food the rest of the day (this from a guy who always orders 2 dinners when we go out). I can usually eat 1/2 of their sandwiches. Go for the Italian, it's the best!! Casual dining and lots of working guys love this place, it's not fancy, but the food's great!
