We went to OS El Saltillo last night, 12/28/2016, for my birthday. There were 8 of us in the bar area. The waiter was RUDE and UNATTENTIVE. Had to finally ask the manager for drink refills since our waiter kept ignoring us. Ended up not ordering food for half the table. I had been a regular there, but I will not go again.So disappointed!Thanks for ruining my birthday!!!
