Is the following review positive or negative?

I went last week to try this place out and I was not impressed. The cashier recommended 3 flavors (some tangy bbq sauce, mayo, and cheese) for the roast beef so I agreeded to get it. For like 4 tables and 3 of them already eating their food it sure took a long time to get my order. Ive never tasted tap water that bad before and Ive lived in Vegas all my life. Their bathroom was clean and their staff were nice.
negative
