There was a fingernail in my water I waved the waitress over asking her to clean out my cup and make sure it was super clean I didn't want to leave because she would have had to pay for our food my boyfriend got steak not cheap and it wasnt her fault (i looked at her nails they were short) she got me a new water and said she would get us a discount the manager told her im not giving them a discount we were furious at this point forget about the discount but he didnt even come over and talk to us or apologize the server was awesome enough to hand us a coupon for 50 percent off as thats all she could do. Completely disgusted i couldnt eat my food and still had to pay for it we will not be returning to this resturant ever again.
