Saturday lunch at Aloha Specialties is a tradition for me whenever I'm in Vegas. I've typically gotten the local plate: beef teriyaki, chicken teriyaki, spam musubi and mac salad, about $8 I think. Solid, generous portions. My last visit I had the loco moco. Again, solid, tough to screw up a loco moco.
Usually a lengthy wait.
Combine Aloha Specialties with a cup of ice cream from Lapperts (right across the hallway) and you're golden.
