Pho Saigon Noodle Grill

Well how do i start this off. The food it really really good, but the service is RUDE!!!!! Im a regualr customer here because I work locally. I go there every Monday and the staff know me and a fellow worker. We were approached once before by the waitress to ask if something was wrong with the service when we came the previous MOnday. We replied with, no food was good. So she basically said since we didnt leave a tip last time she thought something was wrong. Okay 1st off I thought tips were OPTIONAL!!!!! I didnt know i walked into a five star resturant. The staff never comes back to check on you AT ALL!!!!! NOt even to see if you need another beverage. I was a little offended about that, but i contiuned to go and leave a tip. So basically I went again today and got the usual. The waiter this time asked the same question the waitress did. We responded again with no. He said we didnt leave a tip last time and someone took the merchant copy of check. We responded with we always leave a tip and maybe by mistake took merchant receipt copy. So i guess he was upset and said if you want service you BETTER leave a TIP!!!! Now that right there got me totally pissed and upset!! As he came back from running our check i told him again and repeated what he said "I BETTER LEAVE A TIP"! He said yes and leave more than a $1. Then he proceeded to tell us to not come back and don't pay for the check. So even though the food maybe good, the staff are rude and terrible. So I wouldnt reccommend this place to anyone anymore!!!!!!!!!!
