My family has been dining here for the past three years. We've always enjoyed the retro environment, the service, the live band and the food. Tonight we were a party of 14. My father and I decided to split the bill. After providing the waiter with our two credit cards, he came back with two bills, but not the original bill. When we asked if he had added anything to the tip, his response was ""sometimes the restaurant adds 10%, sometimes we don't."" This didn't sound quite right, so we asked him to confirm. He came back a couple minutes later and said they had added 15%. We found this a bit sneaky and left the tip at 15%. After departing the restaurant, none of us felt right about the way this was handled, so I called and asked for the manager. He (""Mario"") had a real attitude, and said I should have asked for him at the restaurant. When I explained that we had talked to both the waiter and the host about our concerns, he said he ""didn't have time for this,"" and then he hung up the phone. I called back, same thing. Wild. So....either we had an unfortunate misunderstanding, and an unprofessional manager, or El Compadre is scamming large parities. Whatever the case, we won't be coming back. If you're a large party at El Compadre, please check your bill carefully.
