Just experienced same thing...sign in the window and on Google state 3am but before midnight they were closing and rude when we tried to ask for an explanation. Since the original wisdom was a long time ago and the location had not corrected I think it wants a reply not from the local restaurant but rather a corporate reply as to why they maintain poor information.
They are open weeknights til 3. There are many businesses in the area that have over night worker's for the normal Mon - Friday workweek. Weekend's don't have the traffic.
Michelle that went down on Arapahoe Road I really doubt if they stay open at 3 till 3 in the morning but I know that the chicken soft tacos r I'm not worth any good they upset in my stomach not a good place to really buy those tacos from the best on the menu to me as just a tostada good luck in your search for Spanish foods
I know they are open late on Friday and Saturday. I don't think they are Sundays.
