I visited Sunday night, and was completely ignored after I was seated. Nobody even came to get my drink order. So I walked out without ordering. Nobody batted an eye. I then went to Mexican Inn on Airport Freeway, and had a fine meal with staff that was interested in their customers. In the past, Miguelito's had at least decent food from what I can remember. But the other night they were only half full and they were off their game. The staff were chatting and not paying attention. Also I notice on their menu they add an 18% service charge to parties of 6 plus. If the "service" I saw represents what large groups will get, I would advise them going elsewhere. These additional charges are highway robbery under the best circumstances.
